Received order in less than a week. Bullets come in a nice, old fashion looking box. Bullets, for the most part, are will coated. Exception is that some are not coated inside the lube grooves. Appears to be mostly cosmetic. No leading was experienced using black powder loads. Accuracy was average to good, but not exceptional. Average groups at 100 yards was 2.8” (open sights). Five shot groups at 200 yards averaged 6” (open sights). Will use these for short distance target shooting and hunting under 200 yards. Overall, I am satisfied with this bullets.
