How Come???

OKAY...
I didn't really know what forum to put this in because it involves rifle, handgun and reloading. figured General would be as good a place as any.

Background:

I reload 45 Colt. Currently I put 7.2gr of Titegroup under a 200gr LRNFP bullet (BHN 16 - dia .452). Bullets leave my ruger vaqueros at between 920 and 960 FPS and leave my Win M94 at around 1140 to 1180 FPS.

This is a very accurate load in the rifle and for the first 30 or so rounds very accurate in the revolver (unless I rapid fire it then accuracy goes away very rapidly as the barrel heats up - rifle doesn't care how fast I fire it).

The Ruger Vaqueros lead up pretty badly whether I slow fire or rapid fire. In fact so badly that once when I fired around 100 rounds out of one in a session the cylinder started to feel like it was on the edge of binding.

The Winchester never leads - ever. I've never pulled a bit of lead out of that barrel and I run a Hoppes lead removing tool thru it about every third shooting session. The same tool comes out coated with the stuff when pulled thru the revolvers.

Question:

HOW COME? I just don't get it. Why do the revolvers lead up so bad and the rifle not at all. I've taken to loading cartridges for the pistols with FMJ bullets which solved the problem but increased the cost of 50 rds by 30%.

Is there anything I can do to troubleshoot the problem. What might be the probable causes and what might the fixes be?

As always - thanks for sharing...

Werewolf,

I'll go ahead and leave your thread in Gen'l for now because as you say it is very general. If it turns out you don't get the answers you're looking for here, drop me a PM and I'll move it over to Reloading where different people will see it.

Rugers, especially in .45, are nororious for having tight cylinder throats.
Squeezing lead bullets through those tight throats is a sure recipe for leading.

The throats are in essence resizing the bullets as you fire them. The more lead that builds up the tighter they are sized and the more lead they shed.

Get your cylinder properly reamed and your leading problems should all but disappear and your accuracy wil improve dramatically.
