It’s crazy how barrels and brass combination will change speed.
I’m running a 26” Bartlein barrel, Peterson SRP brass and 41.1 H4350 gives me 2770 .. almost 200 fps slower with a longer barrel!
Interesting!

Haha no kidding. 136s at 2942 is 26" 6.5 PRC territory.
I run 42.2gr of H4350 in my 24" Tikka with 140 hybrids for 2700fps using Lapua brass. It took 43.4gr of H4350 to hit 2800.
