[QUOTE="codyadams, post: 1639670, member: 87243"] Another update. Mag box was fitted and feeds nicely with .270 ammo, just need to clean up and polish the edges. It fits snugly in the mag well. The only hurdle now is figuring out how to attach the follower spring to the floorplate, but that will wait until the rifle gets back from the smith. After fireforming a few rounds I will also likely modify the feed lips slightly to accommodate the sherman cartridge. Last week my smith said he had it tore down and was just waiting on the reamer, which he said would be there in the next couple days, so hopefully we will have the rifle soon and can start some COW fireforming. As a side note, we are doing a second .270 Sherman at the same time, on a Ruger m77 action. My other cousin didn't have the money for a new barrel, but his factory .270 win barrel shot sub MOA with factory ammo, and has under 200 rounds on it, so he is having it reamed to .270 Sherman. Also, he lives in California, so is limited to copper bullets, and since it is the factory barrel, is a 10 twist. So....he will be shooting the 128 Badlands Bulldozer out of a .270 Sherman!! Should be a screamer!!! [ATTACH=full]134908[/ATTACH] [ATTACH=full]134909[/ATTACH] [/QUOTE]
