My intensions are for an AR build, so 2.260" mag mag length. I know my avatar doesn't meet my forum name, but I'm pretty much an AR person. I'm just looking for something in a shorter AR (15's) than the AR10's which the 6arc should do it, but trying to stay away from the needwhores or any whornady line. The 22-250ai is already the 22creed before the creed was born performance wise and beyond! All though I do own multiple 6.5creeds (AR's) and 1 6.5prc (AR also) and no short action standard bolt faced BA's. 338lm is my longest range weapon I have, so owning 308win, 300bo,7-08rem (on the way) 6.8spc, 6.5creed, 260rem, 6.5gren, 243win and 5.56/223 in AR's I was just looking for a different 6mil with a better offering than a 6x45 with decent speed and range for mainly 90gr pills. I don't have an annealer (which would be a tremendous help) for making brass of a 6.8spc to a 6spc. This gives my kids something to play with for hog, coyote and other vermin hunting. Keeping barrel range between 16-20" and a minimum velocity of 2,700 in a 16". 75's are the lightest I'll shoot and 112's the heaviest. Maybe a little off subject, but who cares is it possible to make 6creed, 6xc or similar brass from 243win? Probably not? Having a 22-250ai necked up to a 6mil would look to be a better option than the 6creed.
