Goodness! Is that (47.7gr) even safe? Lol! I’m doing some load dev on a new custom 6.5cm with a 22” Bartlein using H4350 and 140gr Berger Elite Hunters; and when I had someone run quickload for me it hit 63,091psi (max saami pressure) at 43.5gr. Just seems like a LOT of powder and (potentially) a lot of risk, the smoking speed notwithstanding. I have a 24” Savage barrel (on another Creedmoor) that produces consistent >.4moa to 600yds w/ 140gr Nosler BT’s doing 2825fps average and ES/SD in the single digits using 42gr of H4350. Seems like you could find a milder load with AT LEAST that accuracy that doesn’t stress your brass or push over the safe pressure limits. I love speed, probably more than many, but safety is always #1 for me.
Far be it from me to tell another man what to do - if it works for you, then carry on! Lol! Just trying to look out. I guess I’ve hit that age where I’m in old worry-wart! Lol!
