[QUOTE="Trickymissfit, post: 1015059, member: 25383"] may I offer you a better suggestion: build a 6mm/250AI instead. Nothing but a 22-250AI necked up to 6mm. Use factory .243 brass, and cut the neck a little on the long side. I shoot this combo, and it will shoot 105's a tick under 3100fps, and ought to shoot 90 grain bullets at 3200fps. You'll never begin to get close to the mag length restriction. Have a little better barrel life than the .243AI (if it matters much). The other combo to look at is the 6.5x55 necked down to 6mm. You'll gain .07", and have a better neck design than the .243. There's also the 6mm Vias. The shoulder is pushed back about .078", and the case is improved with a 30 degree angle. This round will push a 70 grain bullet faster than a Swift can push a 50 grain bullet (4150fps), but really comes to life with heavy bullets gary [/QUOTE]
