My 243 only does 27'ish with 105's....but shoots them well. Been burning I-4350.....should try another powder but have too much other crap to play with it seems?
My .243 with 26" barrel was getting an easy 3000fps with I4350, and it gets 3145fps after going AI with the same powder. With a slower powder a guy can get 3250fps with a 100gr bullet in the .243AI, and 3350fps is do-able with the 6-06 based on the reports I've read from guys using that combination.
Running .25-06 brass through a die to form 6.5-06 is easy enough, but you're still FF the case. No different than running the same brass in an AI chamber and blowing out the shoulder at the same time. My FF load in my .243AI agg's well under MOA, and is usable for coyotes, gophers, targets, etc, with an 87gr VM at 2900fps.
