[QUOTE="dakor, post: 684556, member: 2204"] So I am getting some conflicting information. I called and talked to Montana Rifle Company and their Gunsmith said if I wanted to I could safely and easily use that action for a 375-408 I would just have to shoot it single shot because of the mag box length. They also mentioned if pressure was an issue with a round higher than the 505 Gibbs what is rated for 39,160 PSI how could they use the action for the 338 Lapua which runs at 60,916 PSI as pressure is pressure according to him. The 408 runs a max PSI of 63,800 so yes it is more than the Lapua but a 378 Weatherby runs a max PSI at 63,817 and I was told that a 378 Weatherby case would not have an issue either and I believe it this action has about twice the iron of the Weatherby action. So my question is what are you guys seeing with this action that it will not handle the 408 case but it can handle the 338 laupa or the 378 Weatherby? The action was a gift from a friend of mine and he is also the one that will be building the rifle so I am in a tough spot here. I really cannot say nope the action is not good enough but I do not want to build something that would not be safe either. So basically I am trying to figure out who is right here? [/QUOTE]
