Where to next?

I know im a nobody but to shoot those bullets you need to make sure you have a 14twist, i also think youre pushing them too fast. Id try the sierra mk if you want to shoot a bullet that light- i think youre doing very well with that bullet (time to move on up). Dont forget the wind flags if you want your groups to get smaller

I’m running a 1:12 twist

I wouldn't clean it after every 5 shot group barrel needs to foul a little.

Even when doing a OCW test. I figured the fouling from start to finish would throw off the groups. Idk. I’m still learning.

The only other thing I would try is some good old H380 with that bullet and see how it compares. Might really surprise you in the 22-250 another good powder to try is CFE 223. Started loads are listed in various books and data bases, if you want to give them a whirl.

I've owned 3 different 22/250's over the years and H-380 and Rem 9 1/2 M primers was always the best powder/primer combo for me along with the 52 gr Berger varmint. Great powder in the 22/250

Sierra advises against using MK for shooting at game.
