[QUOTE="LB, post: 57760, member: 2721"] [b]Re: .22-.250 improved? Make mine a fast twist or don\'t make it at all!!![/b] First of all, congratulations, you picked a couple of calibers that deserves factory recognition, in my humble opinion. It's interesting that you have concluded that your velocity in the previous barrel was the magic. I found it interesting because that is exactly the velocity I am operating at; 3925fps. One difference though. That's the velocity I get with 64/65 grain bullets, either Starke, or Berger. Oh, and another thing, just to muddy the waters, and prove that every gun is different: My twist is 1-14, w/accuracy (well) under ½". Of course, I'm right on the ragged edge, 70 gr bullets do not group at all, and believe it or not; I started my load development with 55 gr Bergers, which grouped very well at one hundred, but when I moved to 200 yards, most didn't arrive. Velocity just under 4,400. That's when a quick call to my gunsmith suggested the heavier weight, and I have been very happy with the results, out to about 550 which is my limit, on game. By the way, I have always used H414, it seems ideal for my application. Lots of ways to go. LB [/QUOTE]
