[QUOTE="codyadams, post: 1517250, member: 87243"] What I would do after getting some HBN coated bullets, is load up like this: 80.5 - 1 shot 82.2 - 3 shots 82.7 - 3 shots 83.2 - 3 shots 83.7 - 3 shots The reason for the first low charge, is after completely cleaning ALL copper and carbon fouling out of your barrel and treating with an HBN/alcohol slurry, your first round fired can have a pressure spike. So fire your first round with a lighter charge. Then, just fire and chrono the loads listed until you match your current velocity of 2980 fps. 2 grains above your current load should get you there or really close. If you get there before you shoot your high load, I wouldn't worry about it, just pull those bullets and reload them with your new charge, and your ready to go. Keep in mind, your new hbn load going the same velocity as your last naked bullet load will have less pressure, so likely a little better brass and barrel life. [/QUOTE]
