I load up 180gr FMJ bullets over 14.3gr of AA#9. The velocity should be somewhere around 1250-1275 fps. I don't shoot a lot of these loads because they are harsher on the gun and brass. I shot a 10rnd mag of these hot loads out of my G29 this morning and all of my rounds were low and left. However, with my normal warm range loads (about 1150fps), I can keep all rounds inside of a paper plate from 7yd to 25yd. I'm thinking that the sting of the recoil was causing my trigger control to be off. However, it might also be that the point of impact of these hot loads is slightly different. I definitely shoot my G19 better than my G29. I've got a 20SF on the way, so I'm hoping that I shoot a little better with the larger gun. Does anyone experience less than stellar performance with really hot loads?
