Shooting B/P and Smokeless same gun different cyl Problem??

[jeeptim]

Got an 1858 Rem with a conversion.
So here's the deal I have 2 B/P cylinders a loading station and 1 conversion that shoots 45L/C I shoot two P/B cylinders and two or so 45L/C and did this 6 or 7 times at the range worked out well. and sure I do a quick clean up every 24 rnds or so am I going to cause any long term problems running like this?

No problems with the gun, but I'm worried about you. You need to shoot more, lots more.

Hello, jeeptim. I have a .38-55 rifle I use both black & smokeless with cast bullets. The only problem I could foresee is someday you were finishing up shooting your .45 long colt smokeless loads..and since bore was relatively clean..only used a smokeless type solvent for clean up. In my rifle, I made sure there was absolutly no leading present after B.P. loads..fouling could be hidden under that lead & do it's damaging work undetected until too late.

Shoot more? Thats 150 rounds plus. Another 50 303 rounds and 200 223 rounds not bad for a day at the range. And I came home with no less then 600 cases now thats a good day

22_5_40 thats the info I was lookin for. So both solvents and a full on inspection after eachshoot is the route I think I will go. Thanx

There's another factor to consider. Are you using hard lead alloy in the smokeless cartridges? Using factory ammo could be rough on your rifling if the gun's barrel is intended for soft black powder-type lead bullets.

The steel used and the depth of rifling in your particular replica could be a problem. Maybe not but 'could be.'

Hey Bob thanx. Yeah I'm using cast lead bullets around 750fps my big deal was the lube from the two mixing in the barrel causing problems. I think I'm just over thinking it.

jeeptim, I've shot smokeless powder in both of my 2nd Generation Colt Peacemakers, then turned around and shot BP in both arms, I cast my own bullets and use a hard lube in my smokeless rounds and SPG lube in the other black powder rounds both are 90% lead and 10% tin which seems pretty soft. Any way when I'm done shooting, having used the BP last I clean the firearms as if I've been shooting BP entirely. In fact clean-up is pretty simple using equal amounts of Murphy's Soap Oil, hydrogen peroxide, and rubbing alcohol. Never had a problem with any of my firearms using that solution. I can't say that I ever shot the smokeless after shooting the BP though.
