Title: 243 wssm
Post by: Thehowler on September 26, 2016, 08:07:49 PM

Does anybody that reloads for this cartridge know which powder Winchester used in the 95 grain Balistic silver tips that were discontinued?
That round has always shot very well in my Browning stainless stalker.

Does  anybody have  a favorite load that works well, they are willing to share for a 22" rifle barrel with a 1/10 twist, deer size round?

Haven't reloaded for the wssm yet but 4350 seems to be one of the better powders for the case with the heavier bullets. Remember the case is sensitive to change in grn
