I just traded a couple of 223 rifles that had sat in the back of the safe for to long on a pair of Ruger American Predator rifles in 22-250. I haven't prairie dog hunted in years which is what the 223's mainly were used for. I do most of the haying now on the ranch and just can't get away that time of year. If I'm not shooting the AR for coyotes I prefer more thump than the 223 offers. I figured these 22-250's would be good truck guns for around the ranch.
I looked up the twist on them and Ruger shows it to be 1 in 10. I know it's not enough for the really heavy bullets, but I was thinking of trying the 69gr tipped matchking in these rifles to see if either likes it. I think a .375 BC and 3200fps would be a wicked combo for coyotes. The Berger book I have shows data from 3250fps to 3314fps with a 26" barrel and a 70gr bullet. I might not quite get 3200fps from the 22" barrel but I should get decent speed. Berger also shows needing a 1 in 9 twist for the 70gr bullet.
I'll honestly be happy shooting standard bullets if the heavier options don't work. I read a lot of reviews of the 65gr Sierra Gameking being a top performer in 1 in 12 barrels even. I have some of them on the loading shelf already. The 50gr Superformance factory loads have worked very well for me in the past to on coyotes.
Anyone have any idea if the 1 in 10 will work well with the 69gr bullet or at least be worth a try? Thanks for the help.
