Ive recently purchased a lwd 10mm barrel used from somebody else, for my G20sf. The previous owner said he didnt do anything to it except run 60 rounds through it, and changed his mind and decided to go in a different direction. He said all the rounds fed flawlessly. But, Im having a little trouble with it, two to three rounds out of every mag doesnt want to feed properly, it will try to feed, hit the top of the chamber, and jam. All it takes to correct it is for me to pull back on the slide slightly, and the primer end of the round will pop up into the proper position, and go straight in, or remove the mag to allow the next round in the mag to cycle up and put the mag back in. The little bit of extra pressure from the round in the mag helps push the primer end of the bullet up so it is in line with the chamber. I was looking at my LWD 10mm to .40cal conversion barrel, and I noticed the feed ramps are different on the two barrels. Could it be that the 10mm barrel I bought used could be an older one, and theyve redesigned the feed ramps on their barrels since then? Which is why the conversion barrel I bought new about a month ago has a different feed ramp, or are the two barrel supposed to have different feed ramps?

Im thinking that perhaps I should install some +10% magazine springs in my mags to help push the primer end of the bullet up some to help line the bullet up with the chamber, but, if the fix is to perhaps send it back to LWD to have the feed ramp worked on, then I would rather do that, if that is where the fix is, being as, I am by no means positive the +10% mag springs will even help at all...

Please instruct me as to what the fix is to this particular problem. Im by no means upset by this, honestly, some problems were expected since the chamber is a fully supported chamber, and thus has a lot tighter tolerances, but, I also know that people can almost always get their guns to feed reliably with these barrels!

Thanks for everyone's time and consideration!

Oh, and I dont reload, Ive used only swampfox 135gr noslers and winchester 175gr silvertips so far and it is just as common with both of them.

I don't have any experience with Lone Wolf barrels but I've heard of the occasional feeding problem with them. They have a tighter chamber than the factory barrel and some people have sent the barrel back to Lone Wolf to have the chamber widened slightly and the barrel started feeding properly.

If it feeds fine with the factory barrel using the same ammo and magazines I'd contact Lone Wolf about it.

How is the chamber support with that barrel? I bet it is REALLY good. I'm thinking you will probably need to polish the feed ramp a bit, and maybe open it up a little. Next time you go shoot, bring some 400-grit sandpaper with you, and lightly polish the little ridge at the top of the feed ramp. Take off a little metal, then run a magazine through. Keep doing that until the feeding issues go away. Once you get home, polish it up good with some metal polish. If you don't want to do that, you could always send it back to LWD. They will open up the chamber for you.

This didn't happen to me with my LW G17 barrel, but I know of several (from the reloading forum) who had to send their barrel back to LW, with a sample of rounds they shoot. LW had to "rethroat" the barrel. It is not uncommon for this to happen. Perhaps that's why you got the deal on the barrel?

BTW, they will rethroat the barrel for free, at least for those guys. Of course, they were on record with LW for just having bought the barrel. In your case, somebody else bought it, perhaps some time ago... not sure how that would work? A call to them might be in order.

Good luck.

Yes, it feeds fine with the factory barrel, never had a problem! Ive posted this same question in the GATE glock pistol forum, where JR, the owner of LWD, is the local expert. So far he has suggested shortening the OAL if I shoot reloads, but hasnt given any more advice since I told him I dont reload. I know he's a very busy guy, and Im sure he'll answer when he can, but for the meantime, I thought I should bring it to the people...

I've had this problem with a couple of my LW barrels that were brand new. I had to rn a bore snake through it every couple mags to keep it running well.

If your barrel hasnt been modified send it to LW and their armorer who is a very nice guy will polish the ramp and chamber for you to help it feed more reliably.

He will work with you until you're satisfied, for sure. They're pretty cool guys.

If it has been modified, polish the feed ramp and chamber yourself or have a gunsmith do it for you but make sure not to remove any metal from the chamber walls/ mouth or the feed ramp unless the problem persists.

It is very tight. Im a real do it yourself kinda guy, if there is something I can do, Id much rather do it myself than somebody else. Ive done every bit of work and installations on my gun thus far. Connector, trigger mechanism housing, new RSA, barrels, striker springs, trigger springs, xs big dot night sights, etc...minor stuff...That being said, Ive never done any metal work to a barrel before, and I know it is very minor, but since Im completely inexperienced, I dont want to risk doing something to ruin the barrel that cant be fixed. I know in the end I will probably end up having to send it back to LWD, I was just wanting to explore other options first.

Here is a picture of my 6" LWD barrel. Mine came from LWD already opened up (I wish they hadn't done it), and you can see where they cut and polished it. Mine feeds perfectly, but has less support. If yours is blind marked, I'll trade with you if you want.

If you look at where they did they did the cutting on my chamber, you should replicate that. However, do it VERY slightly. You want to do as little as possible. To be honest, LWD opened mine up too much for my liking. My stock G29 barrel has the same amount of support (although the LWD barrel is still much tighter). However, this barrel runs 100%.

 

[arushus]

Mine is a stock length, and unfortunately, yes, it does have that big ugly logo on top!

My .40cal conversion barrel has a feed ramp that looks like yours, the 10mm however doesnt have a chamber that has been opened up on the bottom half like yours...

Just use your .40S&W barrel as a guide. You can do it now, at home, but I would recommend doing it at the range. You want to only go as far as necessary. If you go too far, you will reduce the support. The ideal situation is to have perfect feeding with the most support. I'm about to send mine back to LWD and ask for an unmolested barrel.

That is a good idea, Im just really scared of taking too much off I guess. I want to lose as little support as necessary, since, I intend to get into reloading soon, and Im the kinda guy that likes "more power" so Ill definitely be pushing the pressures to the limit!

Im gonna call LWD monday, and if they are willing to do it for free, or for a very reasonable price, then I wouldnt mind sending it in to them.

No comments on the +10% mag spring idea? It is something Id kinda like to install in my mags anyway, I plan on getting a 24lb recoil spring soon, so unless there are some disadvantages to stronger mag springs, Im probably going to install them.

I only need six or seven, so Im going to buy the ten pack, anybody wanna go in on them with me, or buy the other three or four from me?

Edited to add: actually, it would probably be better to just split the 10 pack with somebody, $47.99, plus s+h... I have seven mags, but I should probably keep two as dedicated .40cal mags...

I don't think they will help. They help when your slide velocity is excessive. That doesn't sound like your problem. It sounds like the chamber is just too tight. I just bought some Wolff mag springs for my G29. They make it a BEAR it load that last round.

Ya, I was just thinking that extra pressure pushing up on the end of the cartridge would help the feed issue since it remedies the problem when I pull the mag out a little to allow the next round to move up in the mag, the extra pressure from the next round pushing up on it causes the round to line up properly with the chamber...

 

[arushus]

When the barrel is perfectly clean and oiled, it seems to work quite a bit better...

That's similar to what I thought. As you know, I have been having issues with 155gr Gold Dots feeding in my G29. They would nose up like yours. If I pulled back on the slide, the back of the round jumps up under the extractor, and slides right in. I figured the extra power mag springs might help, but they didn't. My problem is just the rounds being too hot. I think you just need to do some chamber work on the barrel.

Thanks for letting me know that! That is exactly what is going on, so I guess Im calling LWD on monday to see if theyll work on it for me...

Any other ideas?

 

[4949shooter]

Any other ideas?

Other than what Carrier suggested, the only other thing I can think of is to shoot a load of ammo through it and see if the barrel will break in naturally with use.

Edit: Since you said the barrel works when clean and oiled, you could wipe down the barrel with CLP every 50 or 100 rounds to keep it functioning while doing so.
