Hey guys, I hope to get some input from this house. I've have a 700/264 wm take off and it's been laying around for a few years. I thought I'd do something a little different and punch it out to 6.5x300 win mag with a 3.600 OAL. This OAL just fits in the 700 magazine. I'll be using 140 grain bullets for the most part but will also visit 120s as well. In seating 120s, the base of the bullet is flush with the bottom of the neck. So both bullets could be utilized if needed or wanted. I thought of going STW but think the win mag case best for my usage. Anyways... Any here use or shoot this cartridge? I would appreciate any input in load development or speeds attained. Or..any unforseen blocks in the path. Thanks all for your help.
