I wrapped up loading 308 for now. I took delivery of more of the Swiss P styx 168grn, Nosler 165 grn, and Sierra 167grn GK bullets.
I ended up seating them at 2.80ish. That is the mag limit for my AR-10. The AR-10 and the clone obviously have different chambers.
The AR-10 is at 2.835 for max length, while the slower twist clone maxes out at 2.865.
Next time, I plan to do some testing to see if longer cartridges will feed from the M24 clone. Possible somewhere around the 2.850 range. So far, group-wise, I'm not sure if that is necessary, but you know, boredom and all that.
The POF AR-10 is a 1:10 twist compared to the Clones 1:11.25. I can run heavier bullets in the AR-10.
Which brings me to powder. I chose 8208 xbr for my 6.5 grendel, and had been using varget for 308. A couple of posts online mentioned using 8208, with the Clone. So i gave it a go. It does like that powder.
The AR10 not so much, that seems to prefer varget. I'll play more with seating depth and see if i can find a suitible load that works for both
