You will do better than 2500 with handloads. Factory ammo does ~2450 out of a 16".

Excellent.

I did some back of the envelope calculations with AA2200 powder and it looks like the Wolverine, out of an 16" barrel and with 110gr VMax or HPBT bullets, should be good for between 2,390 to 2,480 fps MV, with pressures in the 55,000 psi range, +/-.

Or course you could always use a heavy hand on the powder scale and get the pressures up to 5.56x45 level. Then you could get into the low-mid 2,500 fps range, out of a 16" barrel. I never liked doing this with my 223 reloads, as I cannot crimp primers and pressures in the 62,000 psi + range do not do much for brass life.

OP, i forgot, can a 5.56 be chambered in your chamber or can a 277 w be chambered in a 5.56 chamber?  Or does it depend on the bullet.  

w/ 300 BO you can do that one way or another w/ 556 right?

Thanks. I wish I could have shown it on the video. I was all excited, until I realized that I was zoomed in too tight.




The first shot was a hit, as I found a tuft of hair up by the hole.

You cannot chamber  a Wolverine cartridge in a 5.56 chamber without using a mallet. If you drop the bolt on a WLV round in a 5.56 chamber, you need to do it at least 4 times, having to mortar it out each time to do it again, and eventually you can get it to close on the mangled cartridge.

You cannot chamber a .223 in a WLV chamber as the shoulder on the .223 is .20 further out.

I figured that 556 might chamber in a 300 BO chamber, that could be bad, but worse woudl be 300 BO chabering in a 5.56 chamber.  It can do that

I wouldn't expect them to, seeing as they are designed for 270 Win speeds. I think those are a first run at reliable subs for sale.

We have 200 grain Hawk bullets that are designed to expand at sub velocities, but they're not cheap.

There are not THREE companies offering commercial/"factory" loaded ammunition for the 277 Wolverine.


Mid-South Munitions:

http://www.midsouthmunitions.com/category-s/1834.htm

They have a great selection but have a hard time keeping it in stock due to a strong following local to them.

--------------------------------------------------------

JB's Firearms:

http://www.jbsfirearms.com/category-s/1831.htm

For some reason their store only shows what they have in stock... they also offer 90TNT loads but seem to be out, and are bringing out some 100AB loads shortly.

---------------------------------------------------------


Alpha 7 Armory (Through Outdoor Shooter Supply):

http://outdoorshootersupply.com/collections/alpha-7-armory/277-wolverine

They just started offering last week, and made some fine choices to offer.

In preparation for hunting season, Mad Dog Weapon Systems is offering a 30% off all Wolverine barrels sale using coupon code WLVHUNT at checkout.  Hornady Die sets are also on sale for $84.99 shipped right now - no coupon code needed.

I see you have the 1x7 barrels in 8, 10 and 12"  Are the gas ports all the same?  Or, I guess htey are bigger on the shorter barrels??

Right now we offer, 8.2", 10.5", 12.5", 16", 18" and 20".  We have our first batch of 14.5" coming in today or tomorrow.  Sometime soon we should have all flavors in both 1:11 and 1:7 twist.  I don't think we'll go 1:7 twist on anything longer than 16", though.

Yes, the ports get bigger the shorter the barrel gets with the same gas system (mid-length, carbine, pistol, etc.)  a 12.5" pistol gas barrel will have  a smaller port than a n 8.2" pistol gassed barrel due to increased dwell time.

For WLV headstamps brass I need a 100,000 case order minimum.

For CIP Registration I need a 100,000 round order.

For SAAMI submittal I need to get CIP done first more than likely as it is a smooth transition. My emails and calls don't count anymore... Hornady needs to hear from a lot of other people and/or I need the backing of some well established folks.

reread the OP, looks like case length is 1.535"/39mm.  

It must have a good deal more water and usable case capacity than 300 BO.

okay, so ca 2.5 grain more capacity.  

what about usable space?  Is one or hte other chambering apt to have or less usable powscapacity when seating bullets of comparable BC?

What do you think about a wolverine vs blackout thread where we try to do MV/barrel length comparisons of either similar weight bullts or similar BC bullets?

what kind of gel tests do we have as of yet?  What barrel lengths & what bullet weights?

Do we have any game taking with 8.2" barreled supersonics??

I was thinking about getting an 8.2 for home defense and maybe buying one or another 90 grain TNT load, hoping it may be a good balance of fragmentation and penetration at these velocities?  One thing that is nice about 5.56 for HD is that it has good terminal ballistics with less ovepentatrion than 9mm.  What can we conclude from gel or hunting data??

Thx


ETA: put in an inquiry w/ Hornady about it.  Let's all do likewise so they know how much interest there is.

Okay, so in this other thread I ended up posting up some comparison ballistic figures b/t 300 BO and Wolverine to support the fact that the Wolverine has more effective range, at least in longer barrels.  I figure the data shoudl be here.  A 110g to 110g vmax comparison and a heavy for caliber sturdy hunting bullet comparison.  These are the best comparisons I could come up w/ from ammo data availible for 16" barrels from midsouth munitions and midway.  Ballistics per JBM Ballistics. I did manually input hornady's data for the 120g SST as it is not in JBM's data base.   10mph cross wind, 100 yd zero etc. 1000 ft-lbs range just an admittedly arbitrary data point.  Feel free to check my work.  

A sort of apples to apples comparison in bullet construction and weight:
277 cal Vmax at 2400 fps, .205 SD:
-ME: 1407 ft-lbs
-1000 ft-lbs to 160 yds
-300 yds: 1748 fps, 746 ft-lbs, 11" windage, 21" drop

308 Vmax at 2275 FPS (HSM Load), .166 SD
-ME: 1264 ft-lbs
+1000 ft-lbs to 80 yds
-300 yds: 1497 fps & 548 ft-lbs, 16" windage, 26" drop

A Comparison of Heavier Hunting Bullets:
120 g 277 cal Hornady SST 2150 FPS, SD .223
-ME: 1232 ft-lbs
-1000 ft-lbs to 100 yds
-300 yds: 1594 fps & 677 ft-lbs, 12" windage, 27" drop

300 BO Rem Hog Hammer 130g Barnes Triple Shock at 2075 fps, SD .196
-ME: 1242 ft-lbs
-1000 ft-lbs to 90 yds
-300 yds: 1443 fps & 601 ft-lbs, 15.5" windage, 31' drop



Do we have any 16" muzzle velocity data on the .277 85 grain TTSX flat base?   That would be good to compare like bullet in 277 w/ everyone's favorit 300 BO hunting bullet.  I see some 95 and 110 Wolverine loads but they are boat tail bullets and it would be a bit unfair to compare to the flat base 308 to the 277 boat tails.  

308 Barnes Tipped Triple-Shock X Flate Base, SD of .1666, G1 BC of .289 at 2400 fps (Double Tap Load)
-ME: 1406 ft-lbs
+1000 ft-lbs to 130 yds
-300 yds: 1589 fps & 617 ft-lbs, 15" windage, 23" drop

Here is for the 110 g boat tail for a like weight/constuctio comparison, though this one is BT, the other FB:
110 g 277 Barnes TTSX at 2350 FPS per Midsouth, SD .205, G1 BC: .377
-ME: 1348 ft-lbs
-1000 ft-lbs to 150 yds
-300 yds: 1717 fps & 720 ft-lbs, 12" windage, 22" drop

95 g 277 TTSX at 2575 FPS (per Midsouth) SD: .177,  G1 BC: .292
-ME: 1398 ft-lbs
-1000 ft-lbs to 130 yds
-300 yds: 1732 fps & 633 ft-lbs, 14" windage, 19" drop

I cannot wait for you to do it either.  II'll be happy ot PP a little something something to help out you if you have the time and gear to do some tests, particularly w/ shorter barrels...

I don't have much of money,  but I have far less time.  what barrel lengths do you have in either?

The differences aren't that great but in terms of drift, energy etc, but keep in mind also the SD of the .277 bullets giving more penetration.

What .277 bullets are there that were engineered for 6.8 spc, or just happen to, to expand or frag at lower velocities besides some of all of the lighter barnes bullets?  Any others?  We need those gel tests!



ETA: I think that one of the heavier barnes bullets in .277 may be designed to expand down to about 1600, but most .277 projos need 2000 fps to reliably expand.  What are soem standouts the expand or frag at lower velocities for longer range shooting and/or shorter barrels?

I cannot wait for you to do it either.  II'll be happy ot PP a little something something to help out you if you have the time and gear to do some tests, particularly w/ shorter barrels...

I don't have much of money,  but I have far less time.  what barrel lengths do you have in either?

The differences aren't that great but in terms of drift, energy etc, but keep in mind also the SD of the .277 bullets giving more penetration.


What .277 bullets are there that were engineered for 6.8 spc, or just happen to, to expand or frag at lower velocities besides some of all of the lighter barnes bullets?  Any others?  We need those gel tests!

ETA: I think that one of the heavier barnes bullets in .277 may be designed to expand down to about 1600, but most .277 projos need 2000 fps to reliably expand.  What are soem standouts the expand or frag at lower velocities for longer range shooting and/or shorter barrels?
I only have a 10" 300blk. I don't have a .277 yet I'm hoping to buy a barrel soon.  


Likewise, only I have an 8" 300.

I've been wanting to add a 277WLV to the stable for awhile now, but funds have been short(er) so it's been on the back burner.

I'm still contemplating what barrel length to go with in 277WLV, but will probably go with something in the ~10.5"-14.5" range when I FO.

has anyone chrono'd ANY factory ammo out of the 8.2" barrels, or perhaps the 10.5"???

back on pg 8 of this thread there is some data w/ different powerder and bullets w/ the 8.2" barrel, mostly 90 grain gold dot.  Interestingly, the 110 g vmax average velocity was 2213. Isn't that higher than 300 BO velocities from 8" barrels?

Also compelling is  that average velocities w/ the 90 g gold dot were between 2308 & 2419 w/ the 8.2" barrel.  Now, that is the almost the  MV (2400+) of the 6.8 federal cartridge w/ that bullet out of the 8 or 8.5" barrels in the guns for the Saudi royal guard or whatever.  But this is handloads.  I would like to know MV w/ any of the factory loads.

What 277 bullets fragment or expand at very low velocities?  I'm talking abotu supersonic bullets.  I think I read that Dr Roberts guy, whoever does all the gel testing, said that the vmax frags down to 1900 fps.  Is there anything better?

Thx

ETA: found this big ass table full of info about 6.8/277 bullets w/ all sort of frag velocity info.  It is a little dates though:
https://docs.google.com/spreadsheets/d/1ZR3dtXlCkOLZe9nUCXDX2p3tom2GEo2RN4I0Jj-zwkI/pub?output=html

https://docs.google.com/spreadsheets/d/1ZR3dtXlCkOLZe9nUCXDX2p3tom2GEo2RN4I0Jj-zwkI/pub?output=html

ETA: the standout is the 95 grain Barnes TTSX boattail at 1600 fps expansion threashold.  Midsouth munitinos lists that at 2575 fps from a 16" barrel, that doesn't hit 1600 fps till over 350 yds per JBM Ballistics.  It is making 1000 fps at 130 yds and at 300 yards has 633 ft lbs at over 1732 fps with 19" drop and 14" drift.    

honorable mention goes to the sierra 110 g pro hunter .  The 110 doesn't hit ist frag threshold till after 270 yards assuming 2400 fps MV from 16" barrel and JBM's calc and has 1000 ft-lbs to 140 yds.  At 300 yds it has 656 ft-lbs at 1639 fps, 14" of windage and 22" drop.

I ordered an 18" barrel today, should have the upper built before too long and I'll be able to get started on some gel testing / body armor testing etc.

They got like 3 barrels left longer than 12.5"  Almost bit on a Cerakoted 18"  Out of the case gages..............

It is hard to keep things in stock... I guess that's a good problem to have to rate popularity but bad problem as far as keeping things folks want in.

When we have plenty of barrels, we're out of die sets, when we have die sets, we're out of barrels, when we have barrels and die sets,w e're out of gauges.  LOL.

We just got a small batch of stainless 14.5" and 16" 1:7 twist barrels in for testing... like the others once we have the ports dialed in for supers and subs, we will order a batch of them in 4140 melonite.  It's been a year and-a-half and we're finally getting it all figured out.

Thanks!
Just got the barrel in and waiting on swapping out things in that other upper. Got a family member that wants the barrel that is currently in it; so, I'm good all around. Only the optics & 45° offset sights are going to be pricey to get to finish off.

Curious if there are there barrels for the Savage Axis still available?
The MDT LSS chassis is available for that action and was looking for a 20" medium sporter barrel.
Also, IM me if there is someone that could borg all those pieces parts into one.

were you planning on using factory ammo or reloads?  maybe i could send you an 8" barrel to use if ther aren any others out there that could be used for testing.  Maybe I could send you a little ammo too that you might not already be testing...  I would rather knoow how certain bullets perform before buying parts but i may have to just take a chance.  even if i do spend the moneey i would like some confirmation of what it will do. and i am sure we would all appreciatethe data

would 1x11 be fast enough for supersonics from 7.5-8.2" barrel?  up to the 120 g SST I guess though probably the 110 g would be heaviest I'd shoot.  I do have suppressor.
