Cast bullet and leading

[brickeyee]

"You will have to find a lead bullet that is hard enough and has a good lube on it that your gun likes."

Too hard is as bad as to soft.
.45 ACP velocities are low enough you can use pure lead (swaged) bullets).

Greetings,

Already checked the diameter and it is perfect.

Thank you

Leading

I agree with RCModel That Tornado brush is awsome.
Using cast bullets at high velocity you will more then likely always get some leading. Tame em down a little and it will help. As mentioned earlier also if you are gas cutting and pushing past the rifling your accuracy will suffer.

My colt Ser 70 .45 acp has fire'd over 100,000 rounds in the IPSC games and leading is just part of life. Some cast bullets are worse then others. A lot of guys would do just what you mentioned and fire some hard ball to get the lead out. Other shooters dis liked that practice and would have nothing to do with it. I like to stay on the safe side and never do it. The Tornado brush works way too fast to even think about a risk. Chemicals are chemicals< I dont like them and probably never will. For removing copper OK. But not lead.
The right hardness will help a lot. The smoke is no big deal. Some of the race guns with comps would look like little trains puffing away.

The caliber is .45ACP and the gun is Springfield XD. The XD has a rifled barrel.

I don't know what Springfield is doing, but 1911 barrels have very shallow rifling designed for jacketed GI hardball.

As such, they need hard lead alloy bullets or leading & accuracy will be a problem.

Soft or pure lead bullets will strip out of the shallow rifling and lead up the barrel no matter what you use for bullet lube.

Pure Linotype works best for 1911's.

I think I read this tip here a year or so ago, but Kroil (the penetrating oil) works great for me at removing lead. Swab some down the barrel. Let it sit a while and then run a bore brush down the barrel. Lead seems to come out in sheets.
