OK, will adjust those numbers, for some reason I was thinking 1.585" trim length and 2.260" max. COL...

2.26 is max COAL so that I can load the longer, green bullets within the mag length restriction. The shorter bullets like TNT's, etc will be around 2.190-2.20.  Thanks Vic!

dr69r

do you realize you quoted the entire OP?

at those ranges 300 b is more than sufficient.  Just run it supersonic.  Not to piss on OP's project, juust saying that you might be better served w/ an off the shelf solution.

OP, I like the project.  The one thing that sux about 556 is it teenie weenie bullet.  For those who don't need extreme power but just need better terminal ballistics for medium game out to a few hundred yards a 5.56 based cartridge w/ a slightly bigger bullet is a great idea.  300 B does this, 7.62x40 does it better if you don't need subsonic capability.  Your round will do even better at slightly ranges I suppose w/ less trajectory than 7.62x40.  

the 6.5ppc is a great project too with even less trajectory but give up some terminal performance compared to a .277 bullet I guess.

I appreciate everyone's opinions and perspectives.... It's not for everyone but a lot of people are pretty excited about it as am I obviously

Some preliminary testing last night led to find a 95TTSX loaded to 2.30 is .030 off the lands and leaves aroun 21-22 grains H2O in the case on a small base sized brass made from a chopped 5.56 die. Standard fl dies should give a wee bit more case capacity and 5 stacked round fed/ejected flawlessly from a standard GI type mag.

More to come... Looks like the first Wolverine bark will be heard on the range this weekend.

Keep us updated, as I am sure you will.

I'm still hoping the reduced neck allows it perform with complete powder burn in the 12-13" range...

There was a time when 300BO was not an "on-the shelf" option either.

Just sayin...

Good luck with your testing today.

With a note from the gentleman doing the testing:

I shot the ole girl today, it extremely accurate. First off, I don't have any of the correct powders for this, so don't look too deep into the speed numbers.
Yesterday I made a new die out of an old Lee 223 die by reaming out the neck and turning a bunch off the base, it uses a 6.8 expander and does all of the reforming in one shot. The dies that Mark will be ordering will do the same thing. I also reamed out and shortened an old Lee seater, it works good as well.
When I was checking for where the freebore started( max case length) I noticed it was a bit long at 1.556" the print says it should be around 1.545", I didn't have the gauges yet, so I just went with it, so the trim length was set at 1.545". The gauges came yesterday, and I found that the bolt would close on a no-go gauge, but not on the field gauge. This means that this particular chamber is a few thou deeper than what it should be, wont hurt a thing.

Here is some data using some old Dupont 4198, its too slow and bulky for this case, but its what I have.

I also loaded some 115 Noslers over 22gr. 1200R, these are the first that I shot to break in the barrel, they are not near max, and there is about 3 or 4 grains of room left in the case, it was a safe starting place.

Now, with all of the above ^^^ 16" barrel break-in rounds fired, we have a bunch of other powders inbound to try out as well. These were, well, a bit underpowered. More to come.

The gun wouldn't even cycle, due to A) Underpowered rounds, coupled with B) a leaky gas block/tube, and C) too heavy of a buffer... and potentially D) too small of a gas port.  We've just started testing, though, and we're getting her tuned up.

As long as you are seeing tight groups to start off with, it certainly a positive sign, and that the other small Issues
can and will be corrected once properly tuned with the correct powders and once the actual maximum case
capacity is figured out for that case design etc.

One very Important thing to consider is trying to get the best quality parts available for your budget when building
your Initial test barrel/rifle...It will help to rule out PITA Issues that can develop and slow down development.

Certainly, choosing a ARP 5R Melonited barrel went a long way for the accuracy dept....

It think it will do fine once the correct powders are chosen and the quality components fitted etc.

It's a Pac-Nor barrel with ARP's button, had a Syrac adjustable block on it but switching to a BRT. Aero upper, Colt F/A carrier and an ARP Superbolt. Gas block/tube junction had a leak and I may have gotten one of those random "bad" Syrac blocks.  The gentleman doing the testing had a PRS stock with a heavy buffer in it, which may have been part of the problem as well so that's getting swapped out, too. R&D is fun I tell ya!  Only thing that beats that is trial and error ha!  This bad boy will be running smooth soon once we work out the kinks. Kinks were expected as hey, it's the first one.

You have done an excellent job so far Mark. It will come together soon enough and sub-MOA all day is great to see!

You have mail, Bro.

Thanks gt....

Made it out again today, rifle is cycling fine with all loads shot today. The new die set came from Mark today, it might be a hair too large in the neck area, was getting only .002" neck tension, the die I made is giving .004-.006" I don't know if it made a difference, but the ladder I shot today was with the home made die up to and including 26.6gr, the mail lady showed up with the new die, and I made up the rest of the ladder with it from 26.8 through 27.4, accuracy was not as good with the new die, I think it was because of the neck tension.

I shot at 80 yards today, this is as far as I can shoot from the back door, I didn't want to have to go through the briar bed to set the target out.

Bullet- 90TNT

I loaded these out to 2.270" to try to make room for the powder, they are a little over half way down the neck, probably too long for every day use, but fine for bench work. As soon as we have the right powders, we will shorten the COL up a bit.

Some of JW's pics from today, including brass/primers not showing any severe pressure warning signs, cases filled with 1200R, and the target he mentioned. Obviously, things went WAY better today:

The numbers are looking good THS!

Velocity numbers are looking better, I estimated around 26grs. to 28grs. max. for the case capacity...That 1200-R powder seems pretty good...

Gotta love that 1200R!

Numbers just keep climbing. Now you're cookin!

I had a suspicion it may be a pretty good powder for you cartridge M.

Will there be a reamer available soon?

Would love start on a project barrel.

I'll be able to do reamers in the next month or so... Waiting for the testing to be done so I know all specs are as designed/planned. So far she's shooting sub-MAO without pressure signs, so far so good.

You have worked out a very nice combo.

Can't wait to try it out.

We got 110SPH goin 2500 over 1200R with no pressure signs and ejection at 4:30, .5" at 100 yards.

Very nice M.

That is what I was hoping to see with 110's as a minimum with your cartridge.

Happy for you to see testing is still moving forward in a positive direction.

Its funny I was burned at the stake for telling you this was only going to be 100fps faster than the blackout with the same weight bullet. Your accuracy results are very nice. The 90gr bullets are definitely going to be mainstay of this cartridge. The TNTs are actually decent hunting bullets as well besides being relatively cheap and accurate.

I hear ya, not by me though... And agreed!

Hurry up and get the barrels done I want to go play.

This^

They're ordered!  I'm waiting just like you guys lol.

Figured this could use a bump.

Look forward to seeing more results, when you get some barrels out there and available.

Even though, Apparently I am supposed to be giving you a hard time, because you are working up a non 300blk.  Funny, how people jump to conclusions, and change ones user name to something derogatory.

Thanks... Ordering the WFT's next week... Die sets in a couple weeks, all is good!  More powders coming in, hit our target speeds and accuracy hopes already. Fun stuff.

In!  I was going to build a black out, but I am now waiting to see where this goes.

I agree. I like the idea of a 300 BLK, but know I am very interested in this Wolverine, big time

I made it out again today with some changes with the rifle and ammo, we had a small amount of excessive headspace, so I scratched around in my junk box and found a few bolts, everyone I tried except one would close on the no-go gauge, including the extra that Mark sent, so I went ahead and used the one that would give correct headspace. I don't know who made it, but he needs to be kicked in the nuts, he beveled around the firing pin hole. All of you handloaders know what that means, false pressure signs, just like new Remington 700 bolts. I am going to use this bolt because it gives the correct headspace, and because all of the cases are now made for it.

As Mark stated earlier, we opened up the gas port to .090" to help with cycling, I'm happy to report that the rifle shot and locked back on everything shot today, even the weak-ass LT-32 loads. We wont know for sure if its right until we can test some of the faster powder.

I loaded some 110SPH with some 1200R I was kind of surprised with the results, nearly 2500FPS average on the last string, and the last string was the most accurate.

I loaded two strings of 115CC's with some LT-32, and was disappointed with the results, its too bulky to achieve any good velocity.

I finished the ladder of 90TNT's with 1200R, no more will fit in the case, the last one was heavily compressed, it was also the most accurate.

I'm going to make a shell holder to be able to use the Lee 6.8 FCD, I would like to see how a crimped load will chamber in a 5.56. It takes a minimum of four releases of the bolt to force an uncrimped dummy round in the chamber.

This is the last of the 90TNT 1200R data, the case is full, and compressed. velocity was lower than I was predicting, the temp was 20 degrees cooler than the last time.

Range was 80 yards again.

Ran a pressure test with IMR4227, started showing light pressure at 20.5, and progressively got worse until 22.5 where the primers were showing some pretty good craters. one funny thing to note, the primers didn't flatten out like they do with hotter 110SPH loads, none of them showed much flattening. The headspace was the same for everything shot today. Everything past 19.0gr. cycled with the rifle stock, ejection was at 4:00 with the loads past 19.5.

I shot one string of 120SST's with 1200R under them, these things waste a lot of case space, 23.0gr. was starting to compress. I also shot some 120 Fusions just to see what they would do, I wish these were still in production.

Stopped due to darkness.......

Tried some RE-7 under some 90 Gold dots, 23.9gr. was all that would fit under them, it was compressed. It was not good weather for chrono, partly cloudy, sun in and out, windy, mirage was bad when the sun was out. These gold dots did shoot pretty good though. Ejection was at 3:00 with these loads.

Here is some 95TTSX loads, these shot really good, I was surprised at the velocity, they are only 75FPS slower than SSA tac loads from my 16" 6.8. Need to play with seating depth to see if they will tighten up some, but plenty good enough for hunting. I stripped the bore before, and after shooting this ladder, there was some copper in there afterwards, but it was not too bad. The clouds finally covered up the sun, I think this helped with the chrono readings.

Sir, you are doing fine work.

Indeed!

so when will we be able to buy complete uppers and boolits!

Looking good.

Agreed,

It is shaping up to be some AR goodness! Great work Mark.

Hehe hehe (giggles with anticipation).

Those 90gr velocities are looking pretty nice. Are yall going to try any other powders to eek a bit more speed? 2600 is pretty good for the little pills.

Thanks all. I'd like to take all the credit but I can't. Harrison at ARP put the actual reamer print together and sent it my way, and, I have someone that volunteered to do all of the load data testing. He lives in Florida and has the land/weather/setup to do it... I live outside Chicago and unfortunately don't have any of those things these days.

Right now we are hitting "2650" routinely, consistently with the 90 grain range of bullets and flirt with 2700 on occasion.  We're hitting "2450" with the 110 grain SPH and flirting with 2500 often. One can do 2700 and 2500 with handloading techniques and such without pressure signs.

Unfortunately, powder availability these days as you all knowis sporadic. So far we aree seeing the best results with 1680 and 1200R, to get to those 2700/2500 numbers. We have also tried Re7, H4227, 4198 and Win296/H110.  We got decent numbers out of them but with the H110 we started seeing pressure sooner than we wanted to. That confused me a bit since it's so successful in the BO, but I guess bore size/surface area comes into play just enough to spike it a bit.

Stuff:  I have 50 16" Scout barrels on order through ARP, and will be ordering the Hornady New Dimension die sets on April 2.  The original custom die set I had them make had a neck tension issue but we figured out where they went wrong by making our own die from a cut up 5.56 die and cerrosafing the two to see the differences. Revised die spec is ready and Ben at Hornady is waiting for my call. I'm having custom WFT's getting made to avoid the "chop saw" technique like the BO.  You can go either route but I prefer to just size and trim and be done. I also have live ammo gauges getting ordered/made soon from Sheridan Engineering. I'm ordering their "slot" gauges. I'm in talks with a brass processor that will take your 5.56 brass and send back Wolverine brass, or, sell Wolverine brass direct if you prefer. I'm also in talks with an ammunition manufacturer that will provide loaded/reloaded ammo to those interested.

It's been a fun road, going well and over the next year or two while I recoup the thousands I've spent on developing this thing, and more barrels and die sets get out there, I'll be making the preparations to go SAAMI with it.

I do truly feel this cartridge has a lot to offer the CQB to Mid-Range shooter, the 300 yard medium to small game hunter, the recoil sensitive and the enthusiast.  A friend of mine suggested looking at lightweight 18" Savage pre-fits for youth and female hunters and I think that's ingenious.

I like where this whole thing is going and couldn't be happier. At 2500fps with a 110SPH, we're matching SSA's (not TAC) load in 6.8SPC.  All using cheap and abundant 5.56 brass, bolts and mags. We ran the Wolverine through unmodified pmags, old and new GI mags, etc and it runs flawlessly.

I'll be attending a group shoot at the end of this month with some senior members of another forum I belong to and will let them have at it and let me know what they think.

Good times.

It's been awesome reading the progress of this. Keep up the great work and good luck!

It likes these!

I can't wait to get my hands on a barrel dies ect. Got my bin set up yet THS?

I believe I do... If you haven't PM'd me your full name, then I might not.

Some nice developments this weekend with an alternative die provider and some alternative barrel options in the 10" arena. Will keep you posted.
