I ran some 90 grain GCs through the 22” 1-9” twist .243 the other day. All loads were set at 2.80” (Mag length)
43 grains of IMR 4350 clocked 3175. I shot 1 round each from 41 grains to 43.5 grains.... 5 rounds total, they went about 3/4”.... I’m going to load up a dozen at 43 and run them out to 600.
47.5 grains of RE23 clocked 3210. I only shot 3 rounds of RE23... but they went about 3/4” also. I’ll probably load up a few of these and shoot them at 600 also...
I made up a half-dozen with a nice mellow load of 37.5 grains IMR 4064 that clocked 3050 and shot under 3” at 450 (in a pretty solid wind). BC seems to be spot on at .49.... but 1/4 mile isn’t exactly a stern test of BC.
It looks like they’ll shoot well, and it appears the .490 BC is legit. I’m planning on using them on antelope next week.
