Hopalong Strong Posted November 7, 2011 Share Posted November 7, 2011 Every time I shoot Wild bunch I wind up with a whole lot of leading in the throat of the barrel. What is the cause of this? I understand that leading at the muzzle end suggests not enough lube. There is no leadng there but tons at the chamber end. Any suggestions?

Garrison Joe, SASS #60708 Posted November 8, 2011 Share Posted November 8, 2011 Several possible problems. 1) undersize slugs. Mike your bullets, should be 0.452 or 0.453 for most 1911s. 2) try a harder alloy, if you are not already using a "hardball" type alloy. 3) try a moly -containing lube. Seems better at handling leading for me than the super-hard wax lubes. 4) and, it's a problem that I still fight with my 1911, even after 40 years. Lots less leading than I used to get, but still a little. Lewis Lead Remover when it's tight. Good luck, GJ Link to comment Share on other sites More sharing options...
Hopalong Strong Posted November 8, 2011 Author Share Posted November 8, 2011 Mine is a Springfield GI model. I'm using something close to the #2 alloy My bullest mic out at .450 Link to comment Share on other sites More sharing options...
Marauder SASS #13056 Posted November 8, 2011 Share Posted November 8, 2011 If the bullet is undersized, it will not seal up the barrel. So hot gasses come screaming by the bullet, melt a little lead onto the barrel. Link to comment Share on other sites More sharing options...

And you might want to slug the bore and do a chamber cast. Cerrosafe - just to be sure. Link to comment Share on other sites More sharing options...
Goatneck Clem Posted November 8, 2011 Share Posted November 8, 2011 That's your problem sized @ .450. As suggested earlier use a .452 sized lead bullet that should elimanate leading issues in most ACP barrels. Goatneck Link to comment Share on other sites More sharing options...
Lone Dog, SASS #20401 Posted November 8, 2011 Share Posted November 8, 2011 Lotta folks are using the same 200 gr RNFP for both CAS and WB. If that bullet is sized at 454 instead of 452 what would that do for leading in the 1911? Pressure? Link to comment Share on other sites More sharing options...
Col. Nathan C. Riddles, SASS # 7462 Posted November 8, 2011 Share Posted November 8, 2011 One other thing, run about two mags of fmj ball ammo through your pistol at the end of the day. Just shoot them into the berm after everyone else has cleared the firing line. It will help remove a lot of that leading and make cleaning easier. Learned that little trick in rookie school 45 years ago after shooting swc ammo all day every day for a week. Link to comment Share on other sites More sharing options...
Goatneck Clem Posted November 8, 2011 Share Posted November 8, 2011 Lone Dog....Good point. in WB or CAS if one is using a 45LC Rifle the bullet size can be increased to .454 This will eleminate nearly all the blow back, improve rifle performance and keep your hulls much cleaner of course. Use of .454 in your 1911 will not improve performance Goatneck Link to comment Share on other sites More sharing options...
Dubious Don #56333 Posted November 8, 2011 Share Posted November 8, 2011 Your Springfield 1911 should use .452 size bullets, .450 is a mite small and that's probably the source of your leading issue. Other than that, (leading) you aren't going to hurt anything by shooting them small bullets. Garrison Joe gave ya some good info. I use 200gr RNFP, .452, the same ones I use for 45LC and 45S&W. Most guns in that caliber use 452's not .454 though there are some guns that still have bores that size, older ones for example. Slug the bore to be sure. (you're springfield is most assuredly .452) You could use .454 I suppose, a couple thousanths isn't going to cause pressure problems unless you work up a max load with .452 and then switch to the bigger bullet. The issue however will be they might not chamber. Link to comment Share on other sites More sharing options...
