6.5 PRC go to powder

I was using a buddies chrono. I think that may be the difference?

That must be it. Thank you for posting your numbers. I was expecting to see ~2,725-fps out of a 20” factory barrel and your numbers seem to suppose roughly that.

Ya let me know what you come up with, I would be interested! I do have less than 50 rounds down the barrel so far. I hear they speed up after a hundred rounds or so. Not sure if that’s a wives tale or not.

Echo what has already been said here. H1000 and N565 are pretty standard performers, probably within 10-30fps of each other and relative accuracy depending on what your barrel favors.

N565
143gr and below, usually better results (for me)

H1000
143gr and above, usually better results (for me)

Tried H4831sc, StaBall HD, N568, N570 with varying degrees of success across a few different rifles and bullet weights.

Primers can make a difference as well, I’ve had slightly better velocity/accuracy in my last three builds with 215’s (magnum) vs 210’s (large rifle).

Example:
View attachment 1039507
View attachment 1039508

I have magnums but read several people had varying success with them. So I stayed with the large

Using 56.0gr of N565 and 210m primer got me 2769 fps in a 20” proof barrel with a 147 ELDM

My rifle is a stock Tikka CTR 6.5 PRC. With 58.5 gr of R26 Lapua brass fed 210m and a 140 Sierra game changer I’m getting 3080. With the same load with a 143 gr eldx I was getting 3050. H1000, Retumbo and N560 work well also but R26 is the easy button. I’m down to my last 4 lbs and when it’s gone 60 gr of H1000 is what I’ll use.
