my rifle will shoot 3/4 " groups 1/2" high 12 o'clock center 100 yards with hornady 130 grain sst, there factory ammo not braggin please don't take it the wrong way. now my reloads on the other hand reloader 22, 56 rains of powder all the cases trimmed to 2.53" , 130 grain hornady sst i did lightly crimp them are shooting 4" low and a 1" left , then i went to 57 grains of r22 same everything else and they grouped 3" low and 3/4" to the left. the 56 grain had about a 1 1/4" group and the 57 grain had about a 1" group. i looked at the cases fired and every thing looked all right i was just wondering does any body have a idea what powder hornady uses in the regular ammo not the superperformance stuff? i also measured the finished cases and they were exactly the same as the factory hornady
