this one showed promise, but didn't fool around too much with Benchmark powder in my 22-250, in the 204 ruger Benchmark is THE powder as far as I'm concerned. But my 22-250 likes Varget probably better than anything so that is what I feed it now. I would try these loads above in the order I've listed them. Then, if you can get any Varget powder ever, wrap back and I will give you the details but 35.9 of Varget under a Sierra 55BK at 3,725 is nice, 36.5 under a 55 V-MAX is what I am shooting currently. (My Savage Model 10 Predator Hunter Max 1 LOVED Hornady custom ammo 55 V-MAX's from the Day 1 as I was first doing barrel break-in with these, so I knew I would one day have to return to the 55 V-MAX's and sure enough they are SWEET! in my rifle. But if you want super explosive and a better BC, go with the 55 Blitzkings and don't look back. I didn't find that the 50BK's did terrible damage, but the 55BK's on a ground-hog within say 50 or 75 yards, destroys them!)
Good shooting to you.
