Who has loaded these and how did they work for you? I just shot my first batch tonight. I loaded 15 of each charge. AA#5 6.4 and 6.7. Win 231 at 5 and 5.4. These are the 18bhn action velocity bullets. After each 15 shot string I cleaned the barrel. I had leading from front to back and everywhere in between. My barrel looked like a spider had spun webbing through out the barrel. I know bullet fit is key and I haven't had my barrel slugged to see the true diamiter. My bullets all measure .3995 at the smallest and .400 at the most. I wonder if I load some with a faster burning powder to try and obulate the bullet quicker.
