My gas gun load development

[Burt Gummer]

The 112 match burners are probably the best bang for the buck 6mm bullet out there today. Most important is availability just like you stated. I ran them a little in my gasser but they really come to life in a bolt rig at 28-2900.

The 105 BTHP Hornady bullets are very inconsistent but very forgiving in my experience as far as seating depth and jump....if you can look past the kooky OAL of finished rounds. I don't know for certain if that will work in a gas gun with mag restrictions (the widely varying OAL). They are cheap and plentiful too.

Thanks for the advice. I haven’t gotten around to trying the Hornady 105’s even though I have 100 of them. My goal is long range shooting and the way the bergers and Barnes have performed so far I don’t have much interest in them yet. The Barnes easily fit into my steel ACIS and Duramags.

105, 108, and 109 I run them at 29.4 of lever. I think you will get the results you seek pushing them a little harder. But work your load up to those levels.

I was also using Hornady brass, that stuff is tough.

Thanks for the reply Dino. I have already tried testing both brands of bullets at the max charge weights for CFE223, Lever, and A2520 but my barrel doesn’t seem to like those powders as much. I think it’s trying to tell me to stay in the low 2500 fps range. Wish this wasn’t the case as I had jumped the gun and put all my marbles in LVR and picked up 3 lbs! Looks like I’ll have plenty of fire forming powder ?
