Good advice from navlav8r: 40 gr Sierra Blitzkings shoot best in my Rem 722. The rifle has a slow twist rate, and some barrels won't shoot the heavier bullets well. For my rifle, I have to push 50 grainers very hard to get good accuracy. Those little Blitzkings on top of 21.5 gr of 4198 are awesome.
I haven't owned a 722 in 222 for awhile, but have owned at least a dozen since 1980. I mostly shot 50 grain Sierra Blitz over 22 grains of 3031 in them. Shot my first 'cat, my first coyote, and my first pdog with a 722 in 222. Wish that I still had that rifle, but I had to sell it when we were struggling to keep the bank from calling our loan on our first business. I never had a problem getting accuracy with bullets up to 53 grains.
