Guys I need a little basic knowledge here. I've got a fella wanting to trade me a 22-250 AI with a 7twist at 20" I'm very interested and I have long been wanting to try a fast twist 250 to run the heavy bullets at high speed so what I need to know from some guys that have experience with these is.
What kind of performance over the regular 250 can I expect?
Is a 7twist enough to stabilize the 88 eld and 90gr8 variety bullets, if so what powders should I look at to run in it. H4831/Rl22 burn rate?
What is the expected barrel life, I know its short but just a general idea. 800 to 1000ish?
It appears to be a nice handy set up. 20"M24 contour in a HS precision police style stock. He said he was getting 3550fps with 80gr eld using hybrid 100v. That sound reasonable?
