All that bolt nose needs to do is clear the back of the mag box enough to pick-up the next round. Have you checked your proposed O.A.L. to be sure it will fit in the box with the block removed?
From cycling plenty of rounds through it yesterday I did notice that ther is a small problem extracting, it seems that the extractor blade needs to be shortened abit for the shell to be able to come up to where the bolt will pick it up. Now as far as the bolt stop that seems ok but I will be checking it properly, as I have ordered the bolt stop and extractor blade for the 375H&H, 300 weatherby, so when they arrive i will install them and see how that functions. My bullets fit just fine in the mag and touching the lands with about .100" left to spare.
Thank you
