I ran out to test some 22/250 loads. I have been using Varget with Match king 52 gr bullets they average 3242 fps, they just have not been KILLING the coyotes. We think there going to slow and not opening up when needed. I tested "Rl15, H4895, and IMR 8208XBR with the 52 gr MK. The 8208 was the fastest with 3660 average high 34.5 gr, also tested 33 gr, 33.5, and 34.0. Groups all under an inch with the fastest the best. The H4895 was next fastest, 33.5, 34.0, and 34.5. Fastest was 3583 but all the groups where slightly over an inch with the MK bullets. Rl15 was next in speed 34.5, 35,35.5, and the high fast was 3542 fps. The groups where all very near the 1/2 " mark put the low end was the vey best at the one hole type. but I found that with the Varget too. Looking for some speed. I did some Varget and Burger 52 gr bullets too . 34.5, 35.0, 35.5 gr the fastest was 3576 average the low was 3455 fps. All three groups of 3 shots where at 1/2 inch. SO, It looks like with MK bullets I need 8208 34.5 gr and 3660 fps. But, if I change bullets the 52 gr Burger the Varget going 3576 probable will be the ticket.
39 shots at paper suck I wish we had gone gopher shooting in stead...

Your powder selection is right on track. The 52 grn(others too) 'Match King' is usually accurate but a poor choice on game. They may never 'open up' properly. I'd look to a 55 grn V-Max or stronger bullet, even a gameking. I shot a coyote or 2 with a 6mm Matchking during testing, just penciled right through.
You need better bullets to reliably bag those coyotes.

I just worked up a load for my dad's Rem 700 ADL 22-250. I used almost a max load of IMR4064 behind a Speer 52gr HP. The group at 100 yards was a ragged hole, and that was with NOS factory primed Remington cases straight out of the box, NOT once fired neck sized cases.......I think I'm Done!
At 3600 fps I am pretty sure they would stop a yote.....DRT
