Looking to get anew barrel for my 29 to shoot lead, what is a good one to get? Thanks Jerry ;)
I like LWD (Lone Wolf). Some don't. Bar-Sto is very good, but not as much better as the price indicates. KKM is somewhere in between, and no better than LWD, in my opinion. There are others, and none of them bad, just good and gooder, expensive and less expensive. None should disappoint. Send them back if they do.
jerrydm60, you can shoot lead alloy from you factory barrel. The things to do is inspect the bore for leading issues and look at the end of the chamber for build up that may hamper full battery lock ups.
Other than that I also have the Storm Lake 10mm barrel with conventional rifling, it has worked well also. :D

Jerry, have you attempted shooting lead out of your factory barrel. Reason I ask, is I've had way more Glock factory barrels that will shoot lead just fine, compared to those that won't.
Will be honest with you, of two 29's, only one did not lead up, and of the three G20's I've had, only the last one a 3rd Gen will shoot lead just fine. Not to mention, my first two G20's, a 1.5 Gen, and a 3rd Gen SF model, both bulged brass terribly.
For shooting lead out of Glocks where the factory barrel does not like lead, my money goes to Lone Wolf. Have purchased three to date, all functioned 100%, and all were more accurate then I can shoot. Hope this helps!
As others have said you can shoot lead from a factory barrel, but exercise care.
Also, watch the fit. I would NOT shoot commercial cast .401" rock hard lead and expect good results. But, bullets cast from wheel weights, air cooled with a BHN of 10-12 that are sized .402" will probably work just fine. You may want a slightly harder alloy for absolute top end loads, which you can acheive by mixing 50/50 with linotype if available, or by adding 1-2% additional tin if you don't have linotype.
Good luck.

I beg to differ with you sir. :)
I shoot .401 180gr bullets by MasterCraft Bullets all day long in any and all of my shooter 10MMs without lead fouling or build up of any kind with exception of the Glock 20, I never go over 150 rounds for caution sake. And there is some lead flaking in the factory Glock barrel.
The BHN of the MasterCraft Bullets are 16-18 and they use Magma lube.
One of my Brens is unfired, one is a 45.
My shooters consists of:
2- 5" Bren Tens
1- 4" Bren Ten
SW 1026
SW 610 Classic
Colt Delta Elite
Colt Ultra Ten
Glock 20
EAA Elite Match
Looks like a pretty good sampling of guns - at least for that Bullet Company

I still believe it comes down to the specific firearm, and barrel, when it comes to Glocks. I've had every 9MM in Glocks offerings, and none were problematic with shooting lead. Multiple 45's, again, not a problem. 40's have been 50%, and only 40% success, with 10MM, where shooting lead, wasn't a problem. .401, or .402 mattered not. I believe it had more to do with the finish polish of the barrel, as to whether, or not, shooting lead was a problem. At least that has been my experience.

This.
But lots of folks get scared off when told they need to slug the barrel and match the slug to that diameter +.001" if they want to be assured of a good experience with lead. So, I have just defaulted to telling folks with non-standard rifling to start .002" over nominal bore. YMMV.
Before replacing barrels, try some Lasercast bullets from Oregon Trail (the manufacturer). These cast bullets seem to be the hardest cast bullets on the market and I've been pushing them hard with healthy doses of Blue Dot. MidwayUSA sells Lasercast bullets or you can order them directly from Oregon Trail. Call them and they will send you a pk/5 free sample to try. I would suspect you will be quite happy with the results.
Thanks to everyone for the help, iv been looking at a LW barrel on fleabay and i have used OT lead bullets for my 45s. I will keep you posted on the outcome, Jerry :) :)
I would recommend Storm Lake. Though others would probably get you by just fine.

Storm Lake makes a fine barrel! Have owned a couple myself. I am pretty sure KKM makes a great barrel also. What it comes down to, is they all make decent, to good. barrels, and probably, most, if not all, will out shoot our abilities.
The big point, that I don't believe has been brought up, is the fact of why, most of us, look to purchase an aftermarket barrel. If it's you want to shoot lead, why is it you want to shoot lead? If like me, it's to be able to shoot more, less expensively, why would you pay any more, than you have to, for a barrel, to shoot lead. I did not notice any accuracy gain with the three different manufactures barrels I've owned. Others may have had different experiences. I do, however, see one distinct advantage in buying a KKM barrel. They make a conversion barrel for both the G21, and G30, to shoot the 10MM! :P

For me it is about going to a 6.02" version to add velocity in 10mm.

Curious what kind of velocity increase you've experienced in the 6" over the factory barrel? Only asking, because when I had access to a chronograph, I never compared the two length barrels myself. To be honest, the main reason I first purchased the 6", was because Ohio has mandate of not less than 5 inches on barrel length. When I got the 6", Lone Wolf did not make the tactical length, which is what I have now. Bought it to make the length needed, and mostly, to shoot lead, without concern of leading.
Factory ammo will see an average of 33fps increase. But this is heavily load dependent. Increases can be almost 100 fps for certain loads, maybe more for handloads.

75-150 fps difference compared to a stock G20 length, depending on the load.

Glad some others chimed in with a good answer. I don't currently have a 6" barrel. I do have a Storm Lake 6.02" G20 barrel on the way, but the estimated ship date isn't until 8-13-12. When I get it though I definitely will do some velocity comparison work over my CED M2 chronograph and get back to posting the results in 10mm-firearms.com, and only on 10mm-firearms.com. :D
Included in the comparison will be some Underwood and Winchester Silvertip. Not sure what else yet. Maybe Hornady factory XTP or something. I'ld like to also see if there's a velocity difference between the G20 stock recoil spring and my Wolff 24 pound spring for the G20. Don't know, we'll see.
Quite a spread there with 33- 150 fps! Wish I had compared the two different barrel lengths when I had the chance. If there is a 150 fps gain, then the longer barrel, for that reason, is a sound investment, yet, at a 33 fps velocity increase, not so much. Like I said, with Ohio, mandating 5" minimum length, and wanting to shoot lead almost exclusively, is why I spent my money for the aftermarket barrel. Only going from 1220 fps, to 1250, or, any added accuracy, not that I noticed any whatsoever, is not why I would make an additional 25% investment to the G20. That's just me though!
Have a great weekend everyone! ;D
I'm not sure where the 33 fps figure came from? Even on the BTI website, they show 75-100 fps difference for most of the loads tested between 4" and 6" barrels.
I have never fired a load through mine that only gained 33 fps. Even factory 40 S&W gains more than that.

Yondering, I took the data on the Ballistics by the Inch page for 5" and 6" barrels, derived a difference for each load and took an average.
| Calculation | Value |
| average | 33.89 |
| min | 3 |
| max | 93 |
| Std Dev | 27.07 |
You are correct. When comparing 4" to 6" barrels, the velocity increases average to 102 fps
| Calculation | Value |
| average | 102.89 |
| min | 71 |
| max | 182 |
| Std Dev | 33.7 |
And, just for fun, going from 4" to 5"
| Calculation | Value |
| average | 69 |
| min | 51 |
| max | 90 |
| Std Dev | 15.1 |
This data indicates that factory 10mm ammo is optimized for a 5" barrel. Gains are seen out to 14-16" barrels in most factory ammo, but they are quite incremental past 5" in most cases. I suspect handloads will really benefit those with barrels longer than 5"

I'ld also expect to see a difference between 40S&W-level 10mm factory ammo and Underwood-level 10mm ammo. I can't see that they would be the same across the board, possibly not even close (relatively speaking).
I had the same thought. They do list the buffalo bore 180 at 1399 from 5" and 1428 from 6". This load tops out at 13" with 1586 fps.
But, handloads can be better tailored to a longer barrel.
