Well just got done shooting the mtn. rifle at 20 yards. 60 grains RS, 225 grain aerotip powerbelt. First shot was to the right a tad, i wasnt wearing my glasses and had a hard time seeing my front sight. The other two shots were with my glasses on . I got my moneys worth out of those 3 bullets. But most of all, i am happy to see that she will shoot them accuratly. They loaded like butter too. Which is always nice. My max load will be 100 grains with this bullet and later on when i go for 100 yards, i'll start with that 100 grain charge and start filing down the front sight if i have to. Very very happy that the barrel likes these bullets! Any deer within 100 yards this season is going to get one through the ribs.
