I've got a 1 in 7 twist barrel on a Ruger 77 Mk2... that was formerly a 243, so it has a longer mag, or isn't blocked off like Ruger's 22.250....

with a 75 grain BTHP or A Max, its a flat shooter for sure..

runs 3350s fps with bullets of that weight, seated out of the case more than the usual 22.250 mag length...and with 80 grain A Maxes, it is even more accurate...

I've got some of those 80 grain ELD-Ms on the way from Powder Valley....

Gunner.... RL 15 or IMR 4895 are two powders you will be looking for with those longer bullets...

I thought accurate and velocity would be in the 4350 range, but I was wrong...4064-4895-RL15-Varget are about in the right burn range for those bullet weights...

with that Leupold, you'll have a long range coyote getter...
