Reloading for a 6.5 PRC- what’s next

[coast range]

That’s still good. I have not hit pressure signs but at 59gr I’m at 2785

I'm loading mine at 56.5 gr and getting 2810 suppressed. The same powder charge is 2790 with a bare muzzle.

I took mine up to 58.5 gr and got 2900 fps, but I definitely had heavy bolt lift and heavy ejector swipes at that speed. Mild pressure signs started showing up at around 2850 fps for me.

My barrel is a PVA 7.5 twist for reference.

I'm using the same load and got almost the exact same result with 1x fired brass, 58.5 was sticky during cold weather testing. My velocity at 56.5 is a touch faster avg 2860 suppressed. Easy load to remember, 56.5 N565 lol.

21-1/2" cut down Tikka 8 twist, chamber touched up with AW2 reamer and throated out for 143's.

Who did you have do the reamer?

Kinport Peak Rifles. He's my go to now, great dude. I've got 2 customs at his shop right now that I'll probably do a review on when I get them back.

Retumbo is scarce in my area. I’d like to try it sometime.
