I just bought a Browning Medallion A bolt on 300WSM for my Dad and delivered it last weekend. It has a BOSS so I would say the felt recoil was no more than a 30.06. Wow, does that critter ever bark!!
After bore sighting we got to 1" groups @ 100yds quickly and maintained them. The Winchesster Supreme Silvertips and Supreme Failsafes are available in 150 & 180 grain but be prepared to spend some serious change. $32-36 for 20 round box!Federal is supposed to have a round in the "Premium" brand but I haven't seen any yet.The reason I got him the 300WSM w/ the BOSS was to reduce the recoil as he ain't as young as he thinks he is and the old 300Mag really wallops him.
