My 220 Rocket (similar to 220AI) loves N160 with 50-52gr bullets. I am now using N550 (a little faster that N160, because the store didn't have N160 during my last visit), and it seems to work equally well with a few grains less.
N160 also gives excellent results in our 243AI with 75gr Nosler BTs.
I generally use H414 in all my large case .22 varmint cartridges, but I may switch to N160 because it seems to be less temp. sensitive (H414 can be a sonofabitch in this regard, sticking bolts in hot weather when same load acts perfectly normal at milder temp.), meters almost as well, and gives just as good or better accuracy.
FWIW, N160 is an small-grained extruded powder and somewhat slower than H414, which is a ball powder.
