Ported barrels and lead question

[soundwave]

Hey gang,

I am gonna pick up a barrel to shoot lead through for my G21 and am wondering if there are any concerns with ported barrels.

My thoughts are, they lead might scrape of into the ports therefor damaging the bullet and reducing accuracy.

Any validity to my worries? Anything else I should know?

Thanks!

Curious to know myself. Always wondered this.

Kinda side stepping I also talked with LWD they have plans on making a barrel for the G21C copy the factory porting....Aslo Magna Port here in Michigan says they will port an after market barrel to factory specs for 85.00 2 week turn around.....I also have a G21C sorry I don't know the answer to your question But I did run about 25 rounds of lead threw mine didn't notice any issues....BTW Hey FS whats your turn around on bullets these days?

Not sure about the LW ported bbls but a stock Glock 20c will lead like a mofo out of the ports.:yikes:

2-3 weeks. I'm pretty swamped. I got 15 orders I'm working on. Couldn't cast tonight as I got a sore throat. Lead vapors would be hell.

Do this cause any problems, other than a tougher clean up? Thanks.

imho you wouldn't be "scraping" the bullet and accuracy would not be affected. If you look at the buildup of lead around porting it follows the same pattern as the soot from powder w/jacketed bullets. I've shot lead through a g17c factory ported barrel just out of same curiousity as your post here. result is more like the hot gasses exiting depositing vaporized lead vs shavings or scrapings.
Removal isn't so bad if you let enough build up- it will chip off in a big chuck or two. Inside the barrel lug on my p22 is bad to collect lead deposits behind the can (diameter is bigger than barrel and can, little bit of extra space just sucks lead out of the gases i guess). never seems to build up past a cetain point though and generaly pops out with a little encouragement from a pick & vinegar/hydrogen peroxide)

Also, I remember slick posting once about his 500 comp getting stuffed full of lead, then the bulk of it coming off in one heavy chunk when it was clean time.

It did when I soaked it in Hoppes Elite foaming bore cleaner. Dat foam work real good.

Comp was mudded up jus like cohutt say, vaporized lead residue pattern.

Use ta be a bitch ta clean up, I jus squirt dat foam on, let it sit and hit it wit a little pry force it a come out in one chunk.

Look like new, but it ain't

Here's another thought, based on my personal experience: Even if leading were not a problem with extended, ported barrels, you're just not going to notice much difference in muzzle flip and NO difference in perceived recoil with an extended, ported barrel. Unless you're willing to put up with having a truly compensated barrel, eg., threaded, with screw-on compensator, then you won't be accomplishing much with a ported barrel.

Great info, thank you all.

WalterGA: I have no experience with ported barrels, so this would be a first for me. I wanted to go extended/ported on my G21 because I was planning on shooting some .45 Super eventually. From what you have experienced though, this may not be worth it.

What kind of recoil reduction can one expect with a stout recoiling load such as .45 Super?

My next choice would be a 6" non ported barrel of course.

Thank you.

[WalterGA]

You won't notice much recoil reduction at all with the ported barrel. I shot some .45 Super, .450smc, .40 Super and .400 Cor-Bon through my G21, mostly with a threaded, compensate barrel. Compensators dramatically reduce the slide speed/perceived recoil and muzzle flip. Ports on extended barrels reduce muzzle flip some, but have little-to-no effect on recoil.

I'd either go compensated (my choice) or get the heaviest recoil spring that you can find for shooting .45 Super.

My Taurus Tracker in .41Mag is Ported and it does accumulate lead in the ports. I shoot Plenty of Lead with it,and it seems that the Hard Cast stuff leads a little less. IMO Lead with porting does NOT decrease accuracy. We shoot at a steel plate hanging from chains at 200yds. <-----That Means Nothing,I'm just saying that I wouldnt worry about Lead and ported barrels.

Already running a 22 lb spring on it which functions for light to hotter loads. Thanks for your help, I appreciate your first hand experience.

What type of comp do you have on your 21?

I disagree, hitting a plate at 200 yards with a wheelie says somethin! :thumbsup:

I have a threaded, compensated KKM barrel and a threaded, compensated Accu-Match barrel in .45ACP, plus the same configuration in Accu-Match in both .400 Cor-Bon and .40 Super. Also have a threaded, compensated Accu-Match barrel for my 70 Series GC.

I prefer the design of the KKM compensator over the Accu-Match.

Of course, the great thing about the threaded/compensated barrels is that you simply remove the comp, when you don't want to shoot comp'd!

I had a threaded, compensated KKM 10mm conversion barrel for my G21. Never could get it to extract reliably, so I traded it back to LWD for the KKM .45ACP threaded, compensated barrel.

If any of ya been around long enough to have owned/shot a Grizzly, it was quite popular to pick up a ported barrel in 50AE or WinMag. Irv Stone did a couple of limited runs of both calibers and they were pretty much useless for recoil reduction. Great barrels, but they simply didn't settle the guns down enough to mellow em out like a lotta folks thought.

Grizzlys were fantastic guns, with excellent fit and finish and a lotta bang for the buck, they have died a slow death over the years.

Really very well done guns, but even with a ported barrel recoil was stout. DE 50 using the gas recoil shoot like a pussycat compared.

Yes i agree, my Taurus 44 mag 4 inch is ported. it does accumulate leading, BUT i havent notice it effect accuracy. it can be a pain every once in a while to clean, but no harder than normal cleaning of the gun.
