So out of curiosity any gunsmiths chambering for 6-7prc ? Was just watching a video and 4000 fps with an 80gr bullet seems like a great thing to shoot coyotes with lol. I know barrel life…. Meh 😑
 
Out of curiosity what are your velocities like? I’m a big fan of wildcat stuff that most people don’t have or have even heard of

Right off the bat I got 2,967 FPS during one of my test shots (I'm still just breaking in the barrel) where I was shooting 1-2 shots and cleaning. The above velocity was literally shot #2 on the barrel.

Bullet is a 195 Berger EOL, barrel is a 27" Bartlein - 1:8.

I did up the powder charge one grain as I was testing pressure too (N568), and got a pretty solid ejector swipe along with a good crater. No velocity on that shot though, and I took it back down. I'm sure this barrel will get north of 3K with the 195s once it speeds up.

Some guys report > 3,100 FPS with 190+gr bullets. I don't stand on my stuff hard enough to verify. But basically the 7-300 is a 7 PRC + 200 FPS from my research.
