[QUOTE="Trickymissfit, post: 1389808, member: 25383"] I shoot the 6mm/250AI and like it, but it's also not perfect. Neck length is a little short like the .243. Cases are very easy to form, as you simply neck up 22-250 brass to 6mm, and fire form. Case shrinkage will come in at about .035". Forming them out of .243 brass is a little more work, but shrinkage is about .015". Next time around, I'm going to modify the die for a longer neck length. Then use standard .243 brass trimmed to two inches. This will increase the neck length close to .100", and should seriously increase throat life. The 6/250AI will push a 105 grain AMX to 3000+ fps, and use less powder than the .243. If I don't do this one again, I'll build a 6mm BG. gary [/QUOTE]
