Marrakai, I am curious as to whether you have pursued the idea of a BLR in .416 Taylor. It sounds like a good way to get a quick second shot without taking one's eye off the sights. I would think recoil might be unpleasant as most of the Browning rifles are about seven pounds or thereabouts. The 7 mm magnum should be a good starting point as it and the .338 and .458 win mag are all based on the same parent case. The gear linkage (unless there is a secret to the procedure) could be tedious on reassembly. The barreling is pretty straight forward, though. If you proceed, Please do an article on it. By the way, I have enjoyed your postings immensely in the forums, thank you for sharing your experiences. Phil.
