300WM Load Needed (Berger)
Gentleman, I need a good starting point for Berger 185 VLD's using RL-22 powder. I've turned a 7mm Mag Sendero into a 300WM with a Broughton 5C, 26" HEAVY barrel. I have Fed 215GMM, CCI-250 and CCI-200 primers. Also, would you seat at the lands or jam .010. I have a good load using SMK 180's(.5"@200yds) jumping .020 but their opening up @400 yds (2.5"). Is this the norm? I wouldn't think so seeing that the 1000 BR guy's are shooting 5 to 10 inch groups or so at that distance. I have other powders so other sugestions are welcome. IMR-4831, IMR-4350, H-4831SC and H-1000. Thanks for any help.
