Interesting. Were these USPSA minor power factor loads?When were scoring or taping up USPSA targets shot at less then five yards with plated bullets we often see a spiral shaped pattern of copper on the targets. The pattern is about a inch or more in diameter. I don't know what brands of plated bullets cause this. I'd wager the accuracy is effected.
In all the years of shooting various plated bullets (Berry's, PowerBond, Rainier, RMR, Speer Gold Dot/TMJ, X-Treme), I have not seen 1"+ spiral copper pattern on target but I mostly shoot at 7/10/15/25 yards with pistols and 25/50/100 yards with carbines.
I can do some 5 yard testing at minor PF to see if I can detect any copper pattern on target.
