I have read a few posts on various places online, that the ruger convertible in 45acp cylinder gets really dirty real fast. and that after a few cylinders you need to do a heavy cleaning on it.

Yet if its because residue is buildingup in teh chamber, then how can a bersa 45acp semi auto, for example, or a budget phillipino 1911 run a 200 round box of ammo without that happening?
 
The 45 colt cylinder is the proper fit for the gun as far as the length of the cylinder to the case goes.

The 45 ACP is a very short case compared to the 45 LC but the cylinder is the same length so half the cylinder ends up being a false barrel for the bullet to travel through until it hits the real barrel. There is a lot more chance for the crud to build up in the 45acp cylinder.
In the 45 LC cylinder with the bullet at the end of the cylinder most of it blows out the barrel/cylinder gap or goes down the barrel with everything else. The part that's covered with the length of the case is protected from the crud.

The 45 acp Bersa you referenced has a chamber that actually fits the length of the case.
 
Mine doesn't.
I use 231 for powder and it comes out clean. No difference than shooting a 45 colt. Granted the cylinder has more crud but if the Colt cylinder was as much longer so that it had the same gap between the end of the bullet to the forcing cone it would have similar crud.
Mine is easy to clean after shooting ACP which I shoot more than the colt because I have a lot more ACP cases.
Sorry but some one is feeding you crap.
 
Howdy

I've had this one since 1975. Never heard of the problem you are talking about.

By the way, that part of the chamber in front of where the cartridge case sits is called the chamber throat.
 
BUNK !! I have a COLT NM 45 with 55,000 rounds through it. It has been cleaned four times now if memory serves. NOTE : the 45ACP cylinder on a RUGER BH 45/45 convertible will go a hellofalot longer than that between cleanings.
Matter of fact we burned up 15,000 rounds in 2013, never had to clean ANY of the guns, and six of 'em will be in action in two hours where I will burn up 400 or more rounds in the COLT SAA and COLT NF sixguns. When I am done i will wipe 'em off and put 'em away till next week.
And so it goes...

I would suggest that you go to some other places online, if you are getting info like that...

Or just take note of who is saying that, and disregard them.

The Ruger doesn't get any dirtier than any other gun shooting that same ammo. Period.

You may notice it more, because its a revolver, and more crud gets on the outside of the gun than a semi auto. You may want to clean it more often, because of that, but you don't need to clean it any more often than anything else.

There is a reason to watch the crud build up in the chamber when you are shooting short cases in a long chamber, like .38SPL in .357 Mag or .22 Short in a .22LR chamber, as build up at the mouth of the short case can interfere with chambering the longer case until cleaned, BUT this does not apply to the Ruger .45 convertible, as it uses a separate cylinder for .45ACP and .45 Colt.
 
I haven't shot that much ACP through mine, but I don't recall the cylinder fouling up. I guess I'm going to have to take it to the range next trip and try it out again.
 
.

Now, a .45cal black powder revolver will foul fairly quickly - enough to bind cylinder rotation, once the crud migrates to the cylinder's axle pin.

Fouling isn't too noticable in an autoloader; but due to the cylinder gap, the face of most ANY CF revolver gets somewhat dirty - more discernable on a stainless gun.

That's usually enough, to distress folks accustomed to having their diapers changed frequently...................

well i first read of it on an online gun review site.

Supposedly the 45acp cylinders are supposed to be unloved because the chambers foul up fast within a few cylinders worth. Supposedly because the "nature of the 45acp chambering on the case mouth creates issues with buildup. resulting in cleaning very often during a range session due to an inability to seat cartridges in the chamber"
 
MEOWW!!!

My 1911s gunk up pretty quick,(500 or so rds), probably because I shoot cast and Bullseye, so when I finally get around to cleaning one its pretty much a chocolate mess. Have to take apart the slide to clean the gunk out of the extracter and firing pin etc and the magazine well and feed ramp and in front of the ramp. Maybe the OP is shooting lead in one and jacketed in the other.
 
My .45acp cylinder doesn't gunk up any more than my .45Colt cylinder. I actually like shooting the .45acp better because extraction with the short cases is so much quicker.
 
I have a Ruger SS Bisley .45 Colt/.45 ACP Convertible, shoot nothing but home cast bullets in both cylinders and there are NO problems with either cylinder.

I do admit that when I got the revolver that the cylinder throats were undersized. I used a made for the job Manson Reamer Kit complete with pilots and carefully reamed the cylinder throats to .4525" and both cylinders shoot NRA Bullseye quality accuracy all day long with my own cast bullets. This is a MOST versatile revolver for range use OR hunting.

Here is mine with the .45 ACP cylinder:



FWIW

If this were true, you would have exactly the same problem with an autopistol in .45ACP.

I've been shooting and reloading for the .45ACP for over 40 years, pistols, revolvers and carbines. Never noticed this to be true.
 
I've never had that problem with my 45 convertible. Whoever told you that must have been shooting really dirty ammo and blamed it on the gun. Bullseye or Unique loads with lubed lead bullets would foul any gun pretty quick. My loads of plated bullets and N320 or Clays or Universal can be shot all day long with little fouling. People say that dirty powders and bullets don't matter because they clean their guns every time they shoot but then complain that their gun fouls too quickly. This is why some of us value clean shooting components. A light dusting cleans up a whole lot easier than caked on mud.
 
mmb713, was that a judgemental statement? I'm offended and think you should get some sensitivety training. I'll admit that jacketed loads are cleaner than my cast loads, but it's not like the shooter freezes up after one or two or 50 for that matter mags and the best part is I don't shoot someone elses bullets. Check into that sensitivity thingy.
 
Well, if shooting jacketed ball ammo, I suspect you would have no trouble at all. But with lead (which is all I shoot), I do have a 'slight' condition after a few cylinder full of RNFP, or even TC bullets is shot. There is a slight buildup right at the 'ledge' where the .45 ACP case mouth seats against. This causes a cartridge to not 'drop' right in, but take a bit of force to seat. But I can still go through the box of 100 and not have to 'clean it'. That is the only 'crud' that I know off that is different than the .45 Colt loads. Not a big deal. FWIW, all my .45s (.45 Colt and .45 ACP) cylinders have been reamed to .4525. Have no significant leading problems either in any of my revolvers.
 
It has been my experience that "cleanliness" is more a function of the powered type and bullet (cast or jacketed) than any function of the chamber length.

YMMV
