Bench Time with New .308 Load Workup

[RangeHot]

I've been spending some bench time this week working on a new load for my .308. Trying different powders and bullet weights to see what groups best. Any suggestions on primers that pair well with IMR 4064?

IMR 4064 has been hard to find in my neck of the woods (South Central Wyoming) so I've switched to H414 because I have a lot of it and use a CCI magnum primer, because it's a ball powder 47.5 grains under a155 grain Hornady Match bullet. Good combination for my LR308 and bolt gun both. Work your way up YMMV.

CCI magnum primer, because it's a ball powder

That's interesting
Why a magnum primer with ball powder?
