Thanks for the info gentlemen.
I used to have a 22-250 some years ago that I wish I hadn't sold. Now, where have we all heard that one before. It was a Winchester Coyote that I had a muzzle brake
made and put on by a member of my gun club who was also quite a talented smith. I don't know what the twist on it was, I didn't know much if anything about those things back then truth be told. A friend helped me work up some loads in 50 and 55 grn. Nosler BT's that shot pretty good though. We always did 10 round test groups per work-up load. They shot .5 MOA IIRC with a stock rifle at 100 yds.
I've since shot my buddy's Coyote in 22-250. His trigger seems pretty darn heavy relative to what I remember mine being. Or maybe my memory just isn't so great.
Anyway, right now I'm mostly interested in the 50-55 grainers. As long as the 1:9 twist will shoot the lighter rounds OK, I'll check it out. I've never even looked into shooting any of the heavier bullets. I'll be looking into that though if they really do hang into the wind better.
Keep the opinions coming.
