Coyoteslayer223: I absolutely love my .20 Practical Criterion barreled Model 12 Savage. 1/11 twist. My best coyote load is 22.0 g of IMR 4198 with a 35 gr. Berger at 2.20 oal. Pretty much any powder you can use for .223/5.56 will work in the .20 P, but here's a few to play with.
25.0 g of 8208 w/ a 32 VMax, 23.5 H4198 w/ a 32 VMax, 25.8 g of Reloader 10X w/ 32 VMax
21.5 g of H4198 w/35 Berger, 23.5 g of H335 w/35 Berger
23.0 g of H4198 w/39 SBK, 24.5 g of Reloader 10X w/ 39 SBK,
24.6 g of Reloader 10X w/ 40 VMax, 25.0 g of H335 w/ 30 VMax

The Bergers stay in the Yotes and do little fur damage but cause real trauma on the inside. Most stay inside the yote and they don't usually go anywhere.
