Anyone have a recommendation for a 200G Swift A-Frame for the .300 WSM? I'm trying several 180G bullets this weekend but haven't come up with a recipe for the 200 grainer as of yet.

I'm using 63.5 grains H4350 and a standard (not magnum) WLR primer with a Sierra 200 grain SBT for 2870 fps. With the Swift, with its longer bearing surface, you might try 59.0 grains for a start and work up to 62.0 grains. Avoid the magnum primer though, it increases pressures and you don't need it in to ignite the powder in the WSM case.
