I do use these bullets often and midway always has them in stock so that's nice. I haven't opened my last pound of 4227 yet so i load them with h-110 @9.7 grain @ 2.200" and they work great out of a SIG MCX with a 6 3/4 barrel. I mainly shoot this at my local indoor range but it groups nice at 25 yards

I load the Berry's 220 with 10 grn of IMR4227 and shoot them out of a POF Renegade with 10.5" barrel.
50 yds group was pretty much right on and a 1"+- group.
At 100 yds they dropped about 10-12" ( I shot at this range just to see how much drop)
