I am wanting to do a custom or semi custom (if possible) 6.5mm Mtn Rifle. I have been researching a lot about bullet the seating depth for the VLDs and the problems with the magazines not long enough to be feasible for repeaters. This is the requirements for this 6.5mm build. 1. 24" barrel max 2. be able to shoot the Berger 130 gr and 140 gr and still be a repeater bolt action. 3. 140 gr VLD at 2700-2800 fps. This is where I get lost, can this be done with a standard .260 Rem action without custom machining on the magazine, mag well and throating? Same question for the 6.5x55 swede? Which action should I start with?
