I have a .41 mag Taurus that I'd like to load some lead for. Probably a hard cast 210 grain loaded to about 1,200 for deer close in. I've been told by a few not to shoot lead in a ported gun. But, they can't give me a reason why. I'm assuming just the ports will get some lead build up? That's not a big deal to me. But, I just want to make sure that there isn't something else major that I don't know about.

Thanks!!

I have shot cast bullets, not swaged lead bullets, thru a ported pistol and had asome fouling in the ports, but had fouling from factory ammo also.

It just means a few extra minutes when you are cleaning it.

Porting of rifled barrels should be relieved under the ports to avoid scraping the bullets regardless of materials. It doesn't take much relief, but it needs to be there if I understand all I know. Fouling should not happen other than from combustion materials or maybe some lead that happens to be a bit hot. Or so I've been told. My trap gun is ported, but there is no relief under the ports, and they do collect wad materials along with smoke.

I was advised to fire about a dozen jacketed bullets thru my AR before shooting any cast. The reason given was the gas port inside the barrel may have a slight burr that would tend to collect lead. Other than that, several others have said "Cast 'em hard and fire away".:thumbs:

I do not shoot CBs thru my ARs or my M1As, because it will plug up the gas port.

For Mag N Ported Pistols or bolt action rifles, it takes a little extra cleaning.

klw,

Do you clean the posts when you clean the pistol? That keeps the lead from building up. I only have one ported revolver and everything gets cleaned everytime I shoot it.

I clean each once a year. Usually I've put over 2500 rounds through each by them. No real trouble cleaning the ports. Virtually nothing to remove, regardless of alloy. I just don't think that this is a problem.

You clean your weapons once a year, I clean mine thorughly after each use or when they are handled by the metal parts they get wiped down and a sometimes a swab down the barrel.

I find that clean firearm has a longer life span and has predictable accuracy.

My father who was an avid sportsman around the world would make me clean my rifles and pistols every time I would use them. Plus my drill sergeant would always find a dirty spindle valve on my M14. So I learned to clean my weapons very well.

Once a year. Go shooting five days a week nine months or so of the year. Eight to fourteen guns a day. Each target is scored and the score tracked on my computer using Excel. Accuracy doesn't deteriorate over the year even though the guns aren't cleaned. Of course they don't get very dirty either. All the bullets are cast but there is virtually never any alloy buildup in the barrel. I'll clean out the cylinders occasionally but that's about it. Other than surface dirt nothing gets all that dirty.

Every gun that I shoot gets dirty, but then again I may go out and shoot any where from 20 to 100 rounds, but I always clean my weapons.

I too track the accuracy, but in different notebooks, can you email me a copy of your Excel spreadsheet?

I've love to but...

Years ago I was getting so many virsus that I bought a second computer. Now I have one for just the internet and one for just Excel and Word. So I don't have any ability to send you a copy of the excel spreadsheet. Excel isn't on my internet machine. Sorry. Really wish that I could do that.

But I could probably burn you a copy of my master template and mail you the CD.  Would need an address for that.

On my home network, I have an Ubuntu machine controlling things similar to a router and filtering my net access, plus on my Windows machines have Nortons and other software.

I will be adding one new machine in the next month or two so I will have three PC plus the Ubuntu system, but my work machine is behind the Ubuntu machine as a fire wall and it does work very well.

Microsoft has recently come out with a better antivirus, anti everything software for their systems, my middle son says it works better than Nortons and Ad Aware. I haven't tried it yet.

I have the Taurus 44 mag that has the 4 inch ported barrel. The rifling extends down the barrel for only three inches. The extra inch is bored oversized and has no rifling. Great for cast bullets. I use only 44 Mag cases and download to 44 special levels for target practice. The shorter special cases produce lead buidup at the mouth of the cylinder chambers.

 

ROD!

No matter you have in or on your barrel, there will always be some lead build up. The question is how much and where.

Some weapons get better acuracy after a mild build up from shooting 3 or 4 rounds, others do not. Rifles with gas systems get a build up of lead from shooting cast bullets in the gas port.

A friend with a 357 mag that is ported has a lot of build up from CBs in the forcing cone and the ports. He has to spend some extra time cleaing that pistol. Where I shoot a jacketed round through my weapons and it clears the leading out of the barrel. Some people say doing that is dangerous, other do not. I have never had a problem with a clearing round.

When Bleeber mentioned the lead build-up, I though he was referring to some barrels that actually were shaving lead in the ported area???  Rod

Rod,

That does happen, it depends on the porting job. I have drilled two holes into the barrel and then cleaned up the barrel, but widened the bore and rifling slightly and it did have some shaving. So I wided that area of barrel, near the muzzle out some more, that resolved the problem, but rifling was much lighter because of widening the last last 3/4" of the barrel.

Now I send my weapons out to a place that uses plasma cutting for the ports and there is nothing to clean up.

I have a compensated race gun in .45acp. I shoot lead exclusively through it, but the comp has lead in places where I'll never get it out. Still shoots good though so i really don't care. I have been able to clean leading in a ported pistol with pipe cleaners, so don't see any problems with it either.

Swampshooter,

When I need to, I use the pipe cleaners with the metal bristles.

Doesn't every one have pipe cleaners in their cleaning gear?

Merry Christmas,

Jerry

This was a nice string of posts and I really appreciate the feedback.

I shot some CB out of the gun last weekend, 50 rounds. Just cleaned it with soaked patches, no brush. I looked as best I could at the ports and didn't notice any lead left behind. 50 rounds isn't much I know...I'll keep an eye on it as things go. I'll be shooting more lead in the future as I plan on packing it on a hog hunt in March.

Thanks again!!
