With components costing what they do these days, I keep going back and forth on it. This was my 3rd trip verifying these charges and I’m consistently getting groups under 3/4" with both the 64 grain and 65 grain powder charges. Since this is a hunting rifle and not a precision rifle I was thinking it might be a waste.
@jr1 I saw you mentioned in the other thread you hadn’t started loading for your new rifle yet…c’mon man let’s get going! 
This one’s ready for October!
I usually don’t feel the need to chase anything past half MOA. 3/4 on average and I’m okay with it but I feel really confident with a half.
You don’t have enough data here to show a statistically significant difference for what the best powder load is, but suffice it to say the gun is shooting well. Just pick one of the settings in the middle.
Seating depth can make a difference and sometimes a big one. It’d take you at least 10 shots at each depth to even START to have statistically conclusive answers, and it’s definitely not necessary in this case, but I love chasing the precision.
I know Im slacking. been working on my Nephews 7mm trying to get it shooting. I got side tracked with my 6arc I’m building but I’m about to start my loads for the 7prc
Just a technique, but once I get what looks to be a grouping load “node”, like you have on 64g; then I load the same thing again, in the same 3 pieces of brass, and shoot the load a few hours later, or even over a few days under different conditions to see if it will repeat itself, going back to the same POI. If it does, then I keep testing it; if it wont repeat, then I move on to the next one. Cold barrel, fired across conditions, with repeatability, with consistent POI is, to me, the hunting test. Loads that continue to stack rounds inside an MOA are what I try to develop versus the pinpoint groups, which can be misleading. Good luck.
