Need advice on accurate loads for .308 using IMR 4064,4320 and regular primers

Found Lapua Palma brass (small rifle primer), using CCI-450 primer, reduced velocity standard deviation to single digits. Previously used standard large rifle primed Lapua cartridges and F210M's. I anneal after every firing and quickly outside neck turn just to keep neck tension consistent. Use a Bench-Source annealer that does a great job, turn it on and fire it up. Down to .27 MOA. Rifle is a Defiance Mutant, Krieger 1:12 Palma contour, Eliseo chassis. Bullets used are my own. Not being able to get this rifle down to .200 MOA it was given away.

I'd agree with everything already said, that is use 4064 as your first choice but don't expect 0.2" groups. 4320 has never shone in 308 for me, but it does for some others. Try the Nosler and Sierra bullets first as they usually work well in most factory rifle barrels, although if your Remy's is on the slack side internally you may get best results from the A-Max as they're a little larger diameter than the others.

As for primers, kick off with the CCI-200s - nothing at all wrong with them. CCI-250 (magnum), and Winchester WLR are both 'hot' numbers, and while nothing in handloading or load development is guaranteed, will usually produce poorer results with relatively small charges of 4064 or 4320 in the 308.

Solid info right here. You may be able to get it into the 2's, but 3's wouldn't be nothing to feel bad about. IMR4064 was available for the longest time till reloaders realized some of there favorite .308 powders where not going to be available soon. Then the old favorite IMR4064 started to dry up. If I did not have a stash of H4895 I would have bought the IMR 4064.
