I would like to order a 260 Rem match reamer.
Can somebody give me some suggestions on throat length and neck dia and other important sizes.
I want to accomplish following goals.
cartridge overall length 2.800 with 123 Scenar bullet.
Base brass is Lapua both 243 and 308
With the 243 brass I want a minimum no turn neck. When I neck down the 308 brass it is going to be thicker and then I want to be able to neck turn the brass for perfect fit. So I have a match chamber an can neck turn if I want to.
If anybody has done this please give me some advise, all info is welcome
