40.5 under a 147? The primers look ok.

You’re good. You can go higher.

Reason I asked: A friend of mine uses 40.5 under a 147eld. It does 2650 out of a 26” DTA and is super accurate.

I have a Franken rifle with 28" barreI i put together that shoots that load accurately. I basically started with a copy of the Hornady amax loads and adjusted to there. I've stayed with the 140bthp due to all the price increases. I bought a beater rifle in 6.5 to hunt with. I haven't loaded or shot much due to the prices. Recently got a g19x and started loading for that and the bug bit me again.

Reason I asked was I read some people saying that you need magnum srp or the #41 or br4 primers or you can have problems

You can with some powders. Ball powders, VV, and RE26. There is a YouTube guy who did a test in the cold and got hang fires.
