a Bit of leading

[xtratoy]

My new 480 SBH is giving me a bit of leading. More for the first 15 rounds, not as much the next 15 rounds. I am using Lee 400 gr. bullets cast with recycled range lead. Approximately #2 I would guess, been using it for years with no problems. I Powder Coated them with HF Red 100% coverage and ran through LEE .476 sizer using Alox as lubricant. The bullets really didn't need the Alox but I figured it wouldn't hurt. I slugged the first inch and a half of barrel from forcing cone end and bore measures .475 so it doesn't appear to be a fit issue. I cleaned up the forcing cone with an 11 degree tool from Brownells. Rated to 45 cal but actually tapers to 1/2". I didn't have the brass lapping tool So I made one (11 degreee like the the reeamer) and smoothed it up with 320 grit then 660. I have a real nice FC now that blends perfectly into the rifling. I haven't shot it again to check for improvement. My main concern is that I've heard that PC bullets don't lead so I wonder if I did something wrong on my end. I am using Hoovers load of 14.5 grs. of HS6 with new Starline brass. I resized, belled, the new brass but didn't use a deburring tool on the inside of neck. I am wondering if this is like Berry's bullets that are plated, that can have the plating stripped off with to severe of a crimp and a sharp edge at the neck of the brass. What has been your experience? Here is a couple of pictures before and after crimp.

I know that when loading coated bullets in my revolvers I have to flare the case mouth a little extra and de-burr the inside of the case mouth.The coating is tough but in my experience it will scratch in seating and cause some bore leading.

If you are getting a decent flare on the case mouths I don't believe inside deburring is necessary, I never deburr pistol brass, that just leads to earlier case neck splits. I think you maybe need to shoot a few more rounds to see if the leading is still there. After your clean up work of the forcing cone, etc. you might find you've corrected the problem. Also, just as a test, drop down to 13.5 grs of HS6 with no other changes & see if you get any leading.
I use Hornady One Shot Case Lube on any bullets that are a big tight going through the sizer, sure makes it easier & has no effect at all on powder or primers, been doing it for 2 years & it works great. Make sure its the case lube, not the gun lube.

  This is just a thought. To quote your second sentence. More leading the first 15 rounds not as much the next 15. Consider shooting some jacketed bullets or even using some JB paste to smooth up the bore a little.  Not knocking your gun, but maybe the bore is just a little rough, and this might go away after a little more time.    I think it will.

Bingo. I always shoot jacketed first in every new revolver
