I usually shoot lead, and after about 100-150 rounds I like to shoot a few FMJ to clear the barrel.
Also, if the bore is rough and you have serious lead residue in it, shooting FMJs could cause excessive pressure, damaging the gun.
over the lead and powder residue, making a bad situation
worse. A jacket with a sharp edge chanellure at groove-depth
bore diameter seems like it might scrap lead out, but I am not
going to count on it.
25 years or so, and ALWAYS ran a cylinder full of hot jacketed CCI lawman or Winchester silvertips through it before cleaning it. That pistol shot 1 1/4" 50 yard groups as long as I owned it. So yeah, as far as my own personal experience goes, it's a good practice...
CLIPPER was there lead in the barrel? a good lead load should not lead the barrel.still not a good idea in a rifle
I've heard this FMJ "blows the lead out" from more than one very experienced shooter, and due to these testimonials I would try it if it ever became necessary. But, by the time I shoot enough lead to lead the barrel, I'd imagine that I'd need to clean the pistol anyhow, or my wrist would be so tired that I'd want to clean it and take a break.
I've always wondered about this, can't vote because I don't know and have never tried it, but I'm curious how people will respond to this.!
I shot thousands of lead .38 wadcutters through my .357 Blackhawk over the course of 25 years or so, and ALWAYS ran a cylinder full of hot jacketed CCI lawman or Winchester silvertips through it before cleaning it.
I'm sure it didn't give you any problems Clipper as:
1. The wadcutters were low velocity leaving little if any lead.
2. You were doing this in a Blackhawk, undoubtedly one of the strongest 357s ever made.
Taking it to another end of the spectrum shooting jacketed bullets through a K frame S&W after shooting a lot of lead is the common reason the forcing cone splits on those guns. The lead buildup in the forcing cone when hit by the jacketed magnum compresses the lead causing the forcing cone to split at the bottom on these guns.
This effect is further encouraged by those who say "I only knock the big chunks off the gun and run a few patches down the bore after shooting".
Shooting jacketed after some lead bullets (depending on the hardness of the lead and velocity) probably isn't going to hurt anything but is not a good practice.
The gunsmith in OKC that I use, Al French Custom Gunsmithing, (you can google his site if interested) recommends the practice with no reservations. I've never been convinced though that it should be done. My gut tells me that the FMJ's would just compress the lead down to a thin coating in the barrel and make it harder to get out. Thus I don't shoot FMJ's after shooting lead.
To clean a barrel of any leading I just use those doohickeys (i forget what they're called even though I've got one for .45 and one for .44 cal) that are like a rubber stopper which you wrap a fine brass screen around and then pull thru the barrel. Works great, fast, no chemicals and gets all the lead out.
Bottom line is, when I had loads that gave leading, I fixed the load so it would not lead. See my previous post.
I also would take the opportunity to ask every gunsmith I encountered if such a practice is detrimental to the gun. Without exception, every gunsmith I asked said it was perfectly acceptable.
Now, if you're talking about a gun where the leading is so severe that the actual bore is plugged, that would be different. But I can't imagine anybody who actually cared about shooting, who would allow their gun to get that bad.
My experiences, although a few years fewer than harmonic's matches exactly.
When leading gets bad enough to affect accuracy its a bear to clean out, but this has only happened to me with .22lr where jacketed bullets are not available, but accuracy returned after a good cleaning.
Just clean the gun after every range trip.
LOL! This happened to me while shooting Remington (Green Box) 22s out of a Model 41 Smith and Wesson. When I got back to the house I tried to clean the bore but couldn't even get the cleaning rod down the barrel.
I worked to get as much of the lead out as possible, but ultimately had to go back to the range and run a box of CCI plated bullets through the barrel before I could get it sufficiently clean.
I don't use Remington anymore.
Never had the problem with Federal, CCI or Winchester .22lr ammo.
Not me!! I prefer to clean the barrel thoroughly before switching from lead to jacketed OR vice versa. Have been doing so since I stated shooting seriously in 1964 with no problems. Will continue to do so as long as I shoot both bullet types in same gun. Sometimes an ounce of prevention is worth a pound of cure. YMMV
Good shooting and be safe.
Been doing it successfully for over 20 years.
