Holy Moly. 2833 is STOUT! My barrel is a 24" Underground Tactical, so I'd imagine we'd have similar results. That is great news, brother man. Thank you for posting!

I use the same load 30 grain 8208xbr cci #41 primers with lapua cases 20" bhw barrel only getting 2733 fps with the Barnes 100gr ttsx

That should be about right - many calibers/rifles see about a 25-30 fps gain (or loss ) per inch of barrel length in the 20-26" inch barrel range. So, at 4" shorter than Cory's barrel, 100 fps slower is right on the money. I just bought a box of the 100 gr TTSXs and I think I'll try working up to that load and see what I clock in my AA 24" barrel. Glad I saw this post.

Love Barnes bullets I won't use cup and core bullets to hunt with any more, that being said they are way to expensive to punch paper at least for me I use 108gr lapua scenars to practice with close to same poi as Barnes and HALF THE PRICE

30.3gr 2759fps
30.6gr 2726fps
30.9gr 2729fps
31.2gr 2762fps



I'm a pretty sure 6 hit somewhere right above 5. This was at 200 yards.

I have some that I'll be working up a load for as well. Cory, are you settling your powder with the 30.6gr and higher loads? You can use an ultrasonic toothbrush or your case tumbler to vibrate the powder into a deeper settle in the case.

[cory]

Actually yes I have been doing that with my tumbler, since variable suggested I try that with ablr loads.

[cory]

That's perty! You couldn't ask for any better expansion.

100gr or 120gr?
Muzzle Velocity?
