Please feel free to help me however you see fit, I'm also thinking of an edge, really riding the fence on this one. If I got the right bolt face, could I build this Lapua on a 110 action safely? What about rear baffles (the one that contacts the bolthead) -- anyone have any info on what kind of baffle this would need? I'm thinking of picking up a 300 win mag or 7 mag and using as much of the action/bolt parts as possible, but would I really be ahead of the game getting this caliber over a 270 or what have you if I'm going to change the bolt head anyways? I know brass is way more for the Lapua, but the reloading dies are much cheaper so that becomes less of a factor in my eyes. Feel free to give me any info on these two ideas, and bring up any other factors or issues I'm going to run into with these calibers off a 110 action.
