I can say with certainty that the performance of a barrel changes during an initial number of firings, and the amount of fouling decreases as the barrel is fired. Most barrel break-ins I did on our pressure and accuracy test barrels were monitored from the initial break-in to observe how performance changed. The rifling in the barrel had been smoothed, but the chamber and rifling’s throat cut by the reamer were not polished and deburred. Most custom barrel makers these days take the time to carefully inspect their products to ensure few, if any, machine marks exist in the barrel, and then lead lap the bore to polish and smooth out the rifling.Īll of the pressure and accuracy test barrels I’ve used in the lab were lead lapped.

Bores exhibiting chattering from worn or misaligned reamers and broaches can be a bit rough. Mass-produced barrels usually receive no post rifling lapping, or smoothing, and tend to have lots of machine marks. Barrels are made by several techniques, which provide widely different qualities of finish and rifling smoothness. It comes down to how the barrel was manufactured. Based on my experience, this is largely true. If you don’t break in the barrel properly, it can initially get heavy copper deposits that will be difficult to remove later. These have to be removed or smoothed out before a barrel can shoot consistently, and minimize powder and copper fouling. The premise of barrel break-in is that there are sharp edges, small burrs or rough spots in the barrel left from the manufacturing operations. I’ve heard everything from “there is no need to break in a barrel” to elaborate procedures that approach a surgical operation. You could write a book on all the opinions about breaking in a barrel. This is copper fouling in the grooves of a bore’s rifling. Actual data on anything to do with barrel maintenance is like looking for the Fountain of Youth, which is to say that it is mostly based on opinion or claims made to try and sell you something. What follows is a summary of my findings and what I’ve learned works well. In that time, I broke in and have cleaned thousands of pressure and accuracy barrels, as well as firearms.

I’ve worked in or run a ballistics laboratory for 25 years. Generally, if something works for you, and you are happy with the results, stick with it! However, I’d like to offer some of my practices and experience on the subject of barrel maintenance.

She said a 'dealer (FFL) friend' handled the listings, so maybe he's to blame for the last one.There are as many opinions about breaking in (or not breaking in) barrels, and how to clean barrels, as there are shooters. I was gracious with her newbie-ness on the first two, even though both cost me something, but the issues today warranted such a review. In the last 13 years on Gunbroker have never, until tonight, left a negative review on said platform. One was grossly inaccurate in the description ('works great', but the revolver wouldn't function in single-action mode). Two were outright deadbeats who didn't pay up. In about 17 years on Auction Arms, I only left three nasty reviews, before abandoning said site. Said problems may be easily solved, but still. The item was listed as 'excellent' condition and it has been a problem.She, cluelessly, assumed PayPal handled gun sales. It was listed as accepting credit card, she couldn't, and after some Quixotic back and forth, I just sent her a MO.She listed, and I selected, ground for shipping, but sent it priority mail and I was stuck paying for said.I just sent her details, and left an accurate feedback on the deal. (As this is for my sidekick, I went with a stock that will fit said, and had her initials laser engraved for the grins.)īeyond that, any other ideas? Thanks all. I ordered a nice, hardwood replacement stock from Boyd's.I ordered a new spring and recoil buffer from Numrich.

The stock issue was sort of a surprise, but it now be toast, so that is a moot point.

And, for that matter, perhaps the stock self-destructing. It looks to me the recoil buffer is there, but chewed up, and that explains the debris that came out.

When breaking it down, I noticed some off-white colored, well, crap fall out.

The bolt-hold open issue is caused by a bent spring on said.

So, I did a disassembly, and as far as I can see:

The small, hair-line crack I noticed on the stock became a very big problem this evening whilst running through a few magazines*.

It sometimes takes running the slide back and forth more than once to get it to close with no magazine inserted.

The magazine hold-open doesn't always disengage.

Imagine that, a Gunbroker listing that was full of bullplop. It was listed as in 'excellent' condition. So, I had a Marlin Camp-45 come in recently.
