Have any of you guys used or seen used the 358 Norma mag on game? I decided to have my rifle converted to magnum (open bolt face/M16 extractor/magnum magazine follower) and rebarreled instead of rechambered. I'm going with a #4 Shilen at 24", comes with a 1 in 14" twist. I will be focusing mainly on 200 to 225 TSX/TTSX at first. No big bears for me, but I sure like thumping elk hard! ha
