[QUOTE="Trickymissfit, post: 497221, member: 25383"] you cannot ream a standard .243 Winchester chamber into a standard 6mm remington. The .243's shoulder will not clean up. But what you can do is ream it with a 6mm AI reamer for a 100% cleanup. I would recommend that you do at least a 1/4" shoulder setback to help clean out any throat errosion. With a 3/8th" shoulder setback you could also do a 6/250AI or with a 1/2" setback you could do a 6BG. You need to set the shoulder back as the standard .243 is well known to be hard on throats. Being as you probably have a bunch of .243 brass laying around, I'd do a 6/250AI. This round works very well with 22" and 24" barrels too. gary [/QUOTE]
