Well, I'm finally here. I can't say enough how great a resourse I have found this site through the years. Now, finally, I need some help that the search function hasn't solved.
A while back I worked up some loads that would eliminate leading in my .45 Colt Single Action Armys which have oversized throats. This morning I went out to the range for some sight adjustment tests on one of them. Aside form skinning my trigger finger knuckle while setting my target stand, bleeding all over the place and only firing 15-shots before calling it a day, I found the bore just past the forcing cone pretty well leaded once I was done. WTH!? I had to break out the Lewis Lead Remover for the first time in a while[smilie=b:
The only difference this time is that the temperature was near freezing, and so was my ammunition.
It seems the bullets were obturating fairly well (though there was a little bit of leading in the throats which is unusual for these loads), so the velocity seems to be as usual.
Does lead act differently enough at freezing temperatures to cause leading like this? Or could the lube hardening up in the cold cause that much trouble?
