My new loads shot safely with no signs of overpressure. The speeds were averaging 250 ft/sec faster using I4198, but almost identical to my Berry's plated using the RE-7. Accuracy was not affected and there was absolutely no leading, none, zero, zip, nada! This is turning out to be a very cost effective alternative to gas checks for cast bullets. They require no lube and just plain look cool to boot. I can coat batches of 63 in 10 minutes with a bake time of twenty minutes. In addition to my 458, I also powder coated my cast bullets for my muzzleloader with identical results. I shot the ML over twenty times and never swabbed the barrel! The bullets still rammed easily and cleanup showed no leading.
I am still having issues with unburned powder fouling the chamber and barrel, which can cause the next round to not chamber. This is a problem that I really would like to solve without getting new primers since ordered primers now takes about 3 months for delivery. If anyone knows what I might try to get the powder to burn better, I am open to suggestions. Could this be a result of running loads that are 10k under max? Does anybody else have this problem?
