I have owned three different short mag's. In my opinion the 300 WSM is an excellent cartridge. There have been alot of new cartridges introduced lately. IMO this is one of the few that has merit. First of all it fits in a short action. This feature again IMO makes for a more accurate round, and if wanted, a lighter rifle. I have read alot about the accuracy of these rounds, I can attest that the 300 WSM is indeed an accurate cartridge. I believe the round will be around, because it does have something to offer. Buy some brass and rock and roll. Tom.
