I am shooting loads from 85 through 95 grains of 4895 under Hornady 350 grain RN with Winchester Mag primers, for reduced loads. Works great and VERY easy on the shoulder.
I am also shooting Trail Boss under 405 grain Bullet Barn lead bullets for grouse and plinking loads. These have zero recoil and are a ball to shoot with the open sights on the 460. Start at 20 grains of TB and work your way up till you get a load you like. I am getting 1/2" groups at 50 yards with mine. (You cannot get enough TB in the case to do any damage, just don"t get into compressed loads or the groups will get erratic, stop when it is full to the point the bullet just touches the powder for best results.)
