When does rust and pitting in a rifle barrel become dangerous?]]> Hunting Rifles Ds J https://systemz.online/hunting-rifles/geroeste-loop-hoe-nou https://systemz.online/hunting-rifles/new-ruger-no-1-rifles Sat, 17 Aug 2024 06:46:12 +0000 Hunting Rifles Tripodmvr https://systemz.online/hunting-rifles/new-ruger-no-1-rifles https://systemz.online/hunting-rifles/headspacing-troubles Wed, 01 May 2024 21:18:49 +0000
When does headspacing turn into a problem?

I have had three or four blown out primers in my 308 over the last year or two. Some readers might remember that I asked about it on other forums.

A month ago, when I was sure all possible causes had been checked and fixed, it happened again that the recoil felt funny, the bolt was stuck and the primer blew out.

Yesterday we determined that the headspacing was too much. The bolt closed stiffly with six patches of masking tape on the back of the case. I also have a small recess on the face of the bolt.

The basics of the rifle and load:

BRNO ZKK601 in 308
PMP cases
CCI primers
36.5gr S335
Hornady 180gr SST
2330fps
1.75mm jump

Any ideas or comments on fixing this?

I have hearf several suggestions:
- fire forming cases
- cutting the barrel and chamber
- replacing the barrel completely

What got me thinking about this, was the other day I was looking for some info on lapping a barrel by firing bullets coated with various grades of grit lapping compound starting at about 220 and working through to 600-800 to polish. Apparently high quality barrels come already polished, but poor quality barrels can be rough inside, and thus foul quickly and heavily, which affects accuracy.

Somewhere on a forum, someone warned about using diamond grit as a lapping compound, instead of aluminum oxide or silicon carbide. And this has been repeated time again, saying that the diamonds stick to the barrel and damage it?

Now if I apply a logical mind, copper is softer than steel, which is softer than all three types of abrasive. If you roll a bullet in abrasive against a hard surface, it will stick to the copper. If you fire said bullet down a barrel, the abrasive will embed itself deeper into the copper than the barrel because it is softer. Once embedded in copper, it will still be able to remove material from the barrel because it is harder than steel, and smooth any rough tool marks within the barrel. I don't get how diamond paste can be worse than the other materials, as based on the hardness of the metals, it should always stick to the softer copper.

Nobody explains it properly (if there is a difference). The only thing I can think of is that the commercial kits are made of silicon carbide, whereas you can find diamond based polished in any grit size fairly easily on the internet and it is often cheaper. I wonder whether it boils down to manufacturers using the internet
and forums to protect their product?

For interest sake, diamond is a 10 on a Mohs hardness scale, aluminum oxide or silicon carbide are 9's and glass by comparison is a 5. On a different hardness scale diamonds are 9000 HrV,  silicon carbide 2800HrV and aluminum oxide 1800 HrV. Diamonds are the most durable, silicon carbide is brittle and doesn't last long, and aluminum oxide apparently is not as sharp as the others. Perhaps there is an engineer here that can explain the significance of the above measurements in relation to lapping barrels?

I can think of one or two possibilities, but I won't stand nearby when it fires any number of times!

This lead me to a theoretical question: how does one get rid of a bullet in a barrel?

And is the barrel still functional afterwards?

I once saw a photo of a .38 S&W barrel which had survived five or six stuck bullets. It was full of donuts!

I doubt that a regular rifle barrel is safe to use after a stuck bullet.]]> Hunting Rifles Ds J https://systemz.online/hunting-rifles/bullet-stuck-in-barrel https://systemz.online/hunting-rifles/burgsmuller-22 Mon, 18 Sep 2023 12:15:54 +0000 Anycase, its a beauty of a little thing, dainty and small - actually sized proportionally to caliber if that makes sense. It even looks like a .22 at first glance.
Does anyone know about these rifles, I read the basic factory history, but nothing on the specific .22
