Don't waste your money on the 70 grain Hornady bullets, they do not stabilize in the 22HP worth a darn, at least the older ones I have. I have tried them in 3, 1899 22HP's and never could get them to work very well. The bullet you may want to look at is the 63 grain Sierra .224. I have some very good loads for that using Reloader 7. When I first tried them, they surprised the hell out of me. In my guns they shoot 1" groups at good velocity. I'm away from my loading data and don't want to give you any wrong load weights. Will get back to you here this evening.
