[QUOTE="Trickymissfit, post: 811193, member: 25383"] a few years back I made CAD drawings of the two in layers to see what it took, and the Remington case looked like it needs about .010" on each side to clean up. But he 6mm Ackley as slightly less taper than the .243, and will clean up. If the .243 has much more than 500 shots thru it, it probably is starting to errode anyway. So a setback will get you there. Performance wise the Remington design is better all the way around with a far greater barrel life. Better yet would be to ream the .243 chamber with a 6mm Ackley using a .243AI head space gauge. You'll still have to use 6mm brass or necked down 6.5 Sweed brass, but the barrel's gonna last a lot longer and the neck handles those 105 grain bullets a lot better. gary [/QUOTE]
