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.

Anyone loading for the lighter bullets like Barnes 127gr lrx? All I've tried was the RL26. And that seems to be unobtainium currently, found some H1000 I will working on for my Nosler 24" 1:8 barrel.

What twist rate are you getting? I see barrel lengths but no twist rates? 7vs7.5vs8.

 

[benconfused]

My tikka loves N565 and 147 ELDM with 20 inch barrel suppressed right around 2960fps. Right around .75moa at 100, but when you shoot farther you run it out the smaller it shoots.

Is this a standard 65prc casing you're using or moved it up to a 7m casing?

All 8's.

 

[roadsterguy]

All 8's.

Thanks, saw a couple people thinking 8 wasn't fast enough for the longer bullets.

I just went with standard twists. A 7.5 might benefit a 6mm if you were set on shooting 115's or something.

I haven't shot anything heavier the 147gr. But seemed to shoot just fine, less the 1 moa
