300 Norma Bolt face diameter is the same as most magnum cases, but I believe if you go with 338 lapua you will need a different bolt. I think the 300 Norma sounds exciting but it's also the new kid on the block and every rifle arm magazine loves to talk about new things it sells magazines. Just because the military selected the 300 Norma does not mean it will be that way forever. I reload and 300 Norma brass seems to be hard to find. If lapua started to make it I would be on board. It comes down to this simple question "what's your plans". Shoot holes in paper or kill from a far " hunting".
