Trying to choose two powders to start with.

H110 and something. Would try shooters world socom but would have to order it.

Going to be for deer hunting, so want to keep velocity up.

I could only find LilGun when I got into 350L, and it works well enough for me I stocked up on it.

I think 165gr @ 2kfps from a 12” bbl is plenty spicy. The deer I shot with it didn’t make it far.

I load it for my son.

I use Hornady 170 JSP, 27.4 L'il Gun, CCI Small rifle primer, 2.238 OAL in mixed brass (Hornady and Winchester).

It thumps pigs pretty good out to 100 yards.

I haven't chrono'd the load, so guess on velocity.

I’m going to guess 2100fps from a 12”bbl on that load. Probably 2400 from a 20”.

That charge seems terribly high. I’m running less than 25gr, with a lighter bullet, at around 2.250.

Hodgdon data lists 27.0 - 27.9 with a 170, 27.4 is mid-range.

You loading 125's? That's the only weight I see that starts under 25 grains.

165gr FTX.

Originally got my data in email from a Hornady rep. Couldn’t even tell you what it was at this point, I just know that I stayed inside their range and in this case, found their data very liberal (when normally their max loads are start charges for everyone else).

I went as high as 25.5gr in testing, with no increase in MV. The 12”bbl just can’t make use of the powder. This load shoots fairly well (typically around 1.5moa). The gun can’t really tell the difference, but it does seem to be less blasty, cleaner, and much easier on the brass. My guess is that the chamber pressure doesn’t peak as high simply because there’s more void space in the case.Attachment Attached File


I loaded 180gr PowerPoints up to 25gr as well, which matched the 1950fps approximate of factory Win ammo. The brass/primers said to discontinue that activity, guess lilgun is NOT the ticket for that load. The PPs don’t group so well, but still plenty for 100yd deer ammo. The gun doesn’t like to feed them very much.

Be very careful of lilgun. It has extreme pressure swings. And it is VERY temperamental of temps. It behaves very erratic below 40*. It has a problem of velocity will go down for several grains of powder and showing no pressure. Then it will blow out your primers with a .1gr increase of powder. It is the worst powder there is to load safe rounds.

Get some imr4227 and have safe loads in any condition.

I attributed the primer I blew at that charge while hunting to have been a loose pocket, I didn’t really manage my cases at all.

Oddly I had no issues in June doing load development, which lead me to believe the above.

How can you back up your statement of erratic behavior at “low” temps?

Since I only have one gun in 350, it seems a reasonable conclusion that it was going to let me load more powder than it can burn with no pressure. I’m positive that this is possible in many other cartridges when used in short barrels.

Notice, when it let me load 180s to the same velocity as 165s, with the same charge, I had trust issues and stopped that. Good sense tells me you don’t get a free lunch on that, but might get an expensive ambulance ride.

I want to say that I got the 180PP data from Hodgdon’s website, which is how I started high to begin with. Those were fired the first testing day, where I had absolutely no supporting data.

Any which way, this all leads me to believe the 27gr being used by FB41 is just way too spicy. That’s a LOT of discrepancy between our data in this size case.

Several loading forums. One consistent thing when primers blew was loads worked up during summer. Blew primers in the fall or winter while hunting. I have been reloading this before there were any dies available. Have had all kinds of different problems as this has evolved. Be very careful of your trim length and do not over crimp the bullet. Consistent trim length will give you a very consistent crimp.  All that is needed is to remove the belling from expanding the mouth.

Lots of people say you have to run the cci 41 primers. With ball powders I would also say that. Most of the stick powders are on the slow side of working well. 4227 is not.

Be very careful on the trim length. Do not go under 1.70" You can create a headspace issue if you do. And make sure they are not too long either. Then you can wedge the case into the bullet and have serious high pressures.

Thanks for the advice.

I did pay the premium and bought the hornady dies @dryflash3 I hope you get a commission.

I couldn't find 4227 locally. It's a powder desert here in my area. So...I still avoided H110 and Lil'Gun and went with Ramshot Enforcer.

I also have some starline on back order.

These will be loaded using CCI 450s and 170 gr Hornady Interlok.

The 170gr interlocks did well for me on paper as factory ammo. Think I have a box of them as component but don’t recall doing any loading.

I have 250 pieces of Virgin starline brass. Extremely consistent out of the bag. 1.705

I resized 100 to prepare for testing...cases grew after using Hornady dies to 1.75 ish.

I wanted to trim back closer to 1.70 and went to use the correct according to hornady #15 trim pilot...which is .358 and well obviously was a no go on the resized brass. Not even close.

I used what I had which was  a #13 338 cal...set the cutter up against the case then locked her down and trimmed.

I will be ordering a #14 345 cal and will try polishing a #15 358 down to fit the resized cases... but that I believe will take alot as I don't have any metal turning equipment.

I still need to disassemble the die and measure the expander ball.

The cases primed great. After the first or second firing I will hit then with a pocket uniformer.

On to flaring, powder seating and crimping.

Here is the Lyman data for the 165gr. You can use it for the 170gr but keep the extra weight in mind if you are going to push it.

Range day. I did not shoot well.

16" Ballistic Advantage Hansen Barrel. Geissele Brownells G2S-E trigger. Very Rusty shooter...gusty to 15 MPH. Today it saw its first 90 rounds. First 40 were 145 gr winchester. 1 early fte. Caldwell front rest and rear bag that wouldn't fit on the weird state range benches.

170gr Hornady intl. - 2.50 COAL - CCI450 Primers. Light Lee collet crimp. New Virgin sized and trimmed to 1.705 starline brass

Enforcer

24.5 - 2,146 fps 35 sd 92 es
24.8 - 2,208 fps 49 sd 132 es
25.1 - 2,185 fps 23 sd 67 es
25.4 - 2,269 fps 3 sd 5 es - only 2 registered on chrono.
25.7 - 2,218 fps 16 SD 47 es
26.0 - 2,213 fps 19 sd 46 es

160gr Fusion Blem - 2.50 COAL - CCI450 Primers. Light Lee collet crimp. New Virgin sized and trimmed to 1.705 starline brass

Enforcer

25.1 - 2,230 fps 43 sd 109 es
25.4 - 2,194 fps 38 sd 109 es
25.7 - 2,225 fps 39 sd 115 es
26.0 - 2,346 fps 32 sd 97 es

I knuckle down hard during the fusions they were last. I had 2 acceptable groups with those. 25.4 was 1.62" and 25.7 was 1.56" if I remove a called flyer.

The hornady best was 1.7" at 25.4 amd 26.0.

Once it's broke in and I get back to shooting form... no doubt it will do better. Selling on the fusion load at 1.62 for this year. Start over next year.

Picture of brass first 6 columns from left to right hornady starting with 24.5 gr. Then last 4 columns fusions starting with 25.1 gr.

I’ll take 1.6” for a, what, 150-200yd deer gun.

Hard telling from the pics, but the primers still look fairly rounded. Plenty of velocity.

I just rolled with H110.  Only other powder I had that I could find data for is CFE Black but the velocity was much lower.

Bear Creek 16" Upper

Starline Brass, Tula SR Primer (standard), 170gr Hornady, 26.5gr of H110

All touching at 50 yards, which is good enough for me, had to do a quick load up before hunting season.  90% of my shots are from 0-75 yards so it'll get the job done.

A quick glance at the velocity data shows you are getting a higher velocity with less powder.  I assume this is because of the extreme variation (high ES & SD) and small sample sizes causing the velocity distributions for the two loads to overlap.  While the groups aren't terrible the high variation is bothersome.  Something is wonky here...  Neck tension, crimp, actual powder weights, headspace (trim length consistency), seating depth

Virgin starline. I sized then All trimmed to 1.705.

All crimped with Lee factory collet...I may slightly increase the crimp.

I threw the charges using my rcbs. I didn't weigh every charge. It was throwing dead nuts. I would get it set. Throw three more then charge the brass.

I was shooting a 2.5-10x viper on 10x.

Sized with hornady dies.

First time doing straight wall... actually has a slight taper.

I will tweak the crimp and try again. I also have sbr socom to try for next season.

The thing with the 350 is weird velocity swings. When using a ball powder the vel sometimes keeps going down till it blows a primer. Then it is over what the books say. H110 and especially lilgun do this. I will not use ball powders anymore because of this.

Everyone likes to blame Win brass for this but they are not looking at the big picture. You see all kinds of people that are 300fps over a max load vel when using a starting load from the books.

I like this cartridge but it is not for a beginner to load. This is one gun that I would NEVER buy used. Or barrel. I see loads where guys are showing 2600-2700fps with the 165gr ftx. Out of a 16" gas gun. That would be close to 80K psi or more to get there. No thanks! I like my bolt action running the 165gr ftx at 2196fps and no where near the top loads. I run my 200gr powder coat lead hp bullets at 1900fps and safe.  Plus I like to shoot the 200grs at 1660fps to plink with 2400 powder.

One thing I would suggest is to get ALL of your brass the same length and get a consistent crimp. Do not go heavy. You need just enough so the bullet is not shot forward when it chambers in the ar15. If a bolt gun then just enough to delay forward bullet movement to get a more consistent powder burn. This could be you wide vel span you have

I can’t wrap my head around why it acts so weird. You’d think it’s straightforward like any other straightwall.

2600fps from a 16” is downright terrifying. I don’t think you can even fit enough lilgun in the case for that, but I’m not going to be the idiot to prove it.

With diligent case prep I can push close to 1MOA using the 165ftx. It really does make a difference. For what I’m using it for though… not really worth the trouble. A deer at 50yds or less doesn’t care.

Cases lengths were all the same.

I did chamber and eject a few but didn't notice bullet movement but also didn't measure. I just barely removed the flare during crimping I think I'll try just a kiss more crimp, verify function and try again.

The case in the far right front corner... that primer is noticeably different than all the others and sharing to flatten

165-180gr copper, 200gr powder coated. imr4227 is my goto full vel powder

Plinking lead loads 2400, unique, herco.

This is for a bolt gun. I lost way too many cases with the AR15 BCA barrel I had. The chamber diameter was a lot larger than the Ruger Ranch I have. And the leade was short. It caused the pressures to build and spike too fast. Exacts same loads in the ruger were fine. But the BCA had case head expansion that the FL die would not correct. I ended up putting the die in my lathe and shortened it to size the case down more to fit in both guns. With the tapered case, if you take material off the bottom it sizes the case smaller all along the case.

I ended up selling the upper to a friend that only shoots factory ammo and he was fine with it. I still shoot the Ruger a bunch. But mostly now with just lead 200gr HP bullets.

Interesting, and thanks. I have a 16” Wilson Combat barrel, some Winchester ammo and a bunch of the 160gr blem bullets from American Reloading. Was planing to use Lil’Gun since I have a bunch, but I’ll definitely keep an eye out for abnormal velocity.

Any thoughts on w244 (I have a lot of it), for heavy subsonic 350s? My assumption is NO, too fast, way too fast.

Looks like that powder will make mild 357mag loads.

Works well for me in 45acp. Would be flinging about the same weight bullet at the same speed, but much lower load density will keep the pressure down.

Dubious as to what would likely be a very small charge making enough gas to cycle an AR pattern.

You ought step down to your 25.4gr range for safety. Minimal velocity loss for the .3gr, and much more margin for error. If you can get the groups to tighten up in that range

I think the 2200fps territory will put plenty of horsepower on target for you.

Took my 350L to the range today. Built with a Wilson Combat barrel and using the WC modified 300blk lancer mags. Rounds did not feed. It looks like the feed angle is too steep and the case mouth was catching in the barrel extension. On the plus side, it showed good accuracy with winchester white box, but I had to single feed it. Any thoughts on a fix?

Dura mags. Nothing is done to the 300bkl Lancer mags to work. It is a 50-50 chance like modifying regular mags. Dura makes Ruger, cmmg, and their own so buy which ever is cheapest or available.

After a few minutes of researching the issue that was the idea I had as well. Hopefully that fixes the problem.

I have 20rd duramags and cmmg. They are the same thing.

My problem is with only two rounds in the mag, it wants to ride over and the bolt goes home on an empty chamber.

The feed lips also have an aggressive edge on them and like to scratch the brass.

ETA: do the above mentioned lancer 300blk mags work with 350L, or did I read that wrong?

The Lancer mags did not feed in my rifle. The reviews on them are mixed with some saying they work fine and others saying they don’t.

Be very careful of lilgun. It has extreme pressure swings. And it is VERY temperamental of temps. It behaves very erratic below 40*. It has a problem of velocity will go down for several grains of powder and showing no pressure. Then it will blow out your primers with a .1gr increase of powder. It is the worst powder there is to load safe rounds.

Get some imr4227 and have safe loads in any condition.

Second that, Hodgdon data, 4227 under Hornady 165 gr SST (.355)
