Re: .338 Lapua Loads
I also have a 700P. I have found that 85.5 grains of H4831SC with 250 Hornady HPBT work the best with an average of .46 MOA.
I've been through almost every powder from H4831 to Retumbo using the 250 SMKs. I just tried the Hornady version and the rifle likes them for some reason so I've switched over.
I also take my 700P elk hunting. I use IMR7828 & Sierra 250 grn GameKings which is a great combo.
