Problem with Lonewolf barrel

Got my new G20sf and went out with some new handloads, Lonewolf 4.6" barrel, new guide rod and 22# spring. Loaded the magazine, slide back, released the slide and the round jammed about 45 degree angle part in the chamber. Tried several times with different rounds, same result. I finally pulled back the slide a tiny bit on a jammed round and got it to chamber. It shot and cycled ok for a few rounds then the slide wouldn't go forward all the way, need a gentle push on the back to close completely. This happened several times over about 30 rounds or so. Seemed to get a bit better as the shooting went on. The next day to failure to close during shooting happened a couple of times and one failure to load from releasing the slide with new loaded magazine. I changed back to the Glock barrel and no feeding issues at all.

Talked to Lonewolf and they said send it back it may need chamber opened up a bit and my handloads may be out of spec. Well I wanted this barrel so my brass would deform during range sessions so I could reload. Stock barrel will be used for field carry. They want me to ship it back on my nickel and said they would reimburse my reasonable shipping if there was a problem. They also wanted a few dummy rounds but what will that do if it is intermittent.

My reloads drop into both barrels just fine.

Anybody else have this issue and/or deal with Lonewolf?

If you are handloading it might be an issue of overall round length.

thats my best guess

I have a few Lone wolf barrels and never had a problem. G19 and G21SF. I do not reload, all factory stuff.

Now that I have a better set of calipers, I'll double check my COL.

Yea double check your dimensions, the lw barrel has tighter tolereances and I know on my g37 & g22 the lw barrels have a longer feed ramp compared to the stock glock

Tolerances were pretty close, a tad long. I have since gotten the COL to 1.260 or a tad shorter and I still get failure to feed on first round (slide open) with the LWB. The other issue during cycling has gone away. Does it just need a little wear in?

On another note I had a failure to feed on my stock barrel. Even though it has not been shot much (less than 50 rounds), maybe needs wear in? Either way disappointed with that.

In my G23 from 2000, I don't recall one failure to feed, no idea on round count 1,500 +. It went for while with out getting shot much.

It's probably not your OAL unless you are running them way too long. I've done extensive testing with moly and lead rounds with a lone wolf barrel in my G34. Their chambers are too tight, and this runs to the feeding side of the chamber. Tight chambers and reliable feeding are typically conflicting needs in a semi-auto. Have them open up the chamber a little bit and it will probably run just fine. I personally recommend spending the extra money and getting a KKM drop-in barrel. I've never seen a bad one.

The tighter chamber does make reloading the brass a little easier, but there isn't anything wrong with reloading the brass after shot from the glock barrel. I reload glock shot brass all the time and from multiple calibers. The only reason to switch to a lone wolf barrel is to shoot lead reloads. I've shot lad out of the glock barrel, and figured out how to do it without buildup, but it's a lot of work and you still get some lead to clean out of the barrel.

I appreciate the input, I may just send it in to have it opened a tad after I put a few more rounds through it. As I said my main motivation for getting it was to shoot hot loads and have reloadable brass. My concern is still if they open it up then the brass can deform. Won't it be like having two stock barrels, except for the rifling difference?

Your brass is going to deform anyway. It just matters how much it's going to deform. If it deforms past what the web can withstand, then the brass is dead. Not even the glock barrel allows for that.

It sounds to me like you've been reading too much about the glock guppied brass. Don't believe the hype. Buy an EGW U resizing die and never have to worry about guppied brass again.

Hmm, looked up that die and that is an interesting option. The issue with that is working the brass more.

Shot some full power loads and no Glock smile. On another note I had more FF in my stock barrel, I'll start a new thread.[Bang]

I measured some cases just up from the base on all. Once fired are both with above load.

New unfired - 0.421"
Once fired stock barrel 0.433"
Once fired Lone Wolf barrel 0.426"

just fyi, I found it interesting.

The amount you work the brass with the U die isn't enough to affect the brasses life. I use them on 9mm, 40, and 45s and have brass in all three calibers with 10+reloads using the U die.

.007" isn't enough to really worry about either as for overworking the brass either. The problem with the semi-unsupported chambers like the HK and Glock is getting bulge below where the average sizing die resizes on the case. Then you get a reload that's slight larger than the chamber can handle and it jams and won't fire and won't extract; death jam. This is a problem with brass from some of the older Glock 40 cal models and HK USPs. This is not an issue with the 9mm and 45s. These calibers have thicker webbing in the cartridge cases and they tend to not have the "guppy brass" problem.
