I have a 348, on a siamese mauser action. I did not get the follower, spring, and floor plate, with it. numrich sold me a plate, with instructions how to grind a notch in it. recoil is dropping it. the regular mauser follower is too narrow and won't feed. I remember seeing a follower spring for a siamese that had hinge pins and wire springs, instead of being bent like a normal mauser follower. has anybody ever seen this. does anybody know where to get the correct parts or do I have to get creative? another question, I'm trying paper patching a 220 grain, 338 bullet up to 348. 58 grains of 852 is looking like it will get the pressure, but I am wondering if the 348 twist will stabilize the 338 bullet. I can probably drive it at least 2400. what is the twist on a 338? daryl
