Hello everyone I’m interested in building a 300wsm specifically for competition. It won’t necessarily be an F class build it’ll be closer to a 1000 yard benchrest build. I would like to hear peoples experience with the cartridge. Details like what barrel length to go with. Should I go with 215 bergers versus 220 bergers. Suggested on powders, primers. What’s the expected barrel life. What speeds are achievable with a 29 inch or longer barrel. Pretty much all your standard questions for somebody who has never messed with that cartridge before.
