well I used 24.5grns of same AR2206h for many years with 50-55grn projectiles...still do,have upped it to 25.1grn with a barnes 50grn ttsx with good results on deer n pigs...
the terminal result is like a mildly loaded .243 or .270 using cup n core projectiles but the damage is done in reverse order eg lots damage near side,little hole farside.
