doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com Another potentially stupid question re: wear.

Let's sat there is a gun, with really lots of loads through it, like 500,000 or a million. Can this much "natural use" cause the choke area wear out the inside of the choke area so that the actual constriction becomes noticably less that what it was when the gun was first shot? You know, like shot caps working as sandpaper honing the constriction area a little bit every time?

Also, can this said natural wear, meaning appropriate field and target lead shot loads, cause the barrels cracking at the muzzle, or does this damage require some defect in steel or making, or some undue violence like bad steel loads, to occur?

Sorry if the question is stupid (I've discovered I didn't know a tenth as much as I thought I knew about shotguns lately, so I don't know what's stupid and what's not any more) - or discussed many times before (in this case a link would do). Thank you for your attention.

Is that something you should need to know ?

I'm sorry, English is my second language, and I don't quite follow your question. Are you asking if the answer to this question ought to be common knowledge? Or if I have a specific reason to want to know the answer? No, don't think so; and no, just curious. Home with the flu, got nothing better to do

P.S. If I said "yes", were you going to tell me to get a gun and run 1,000,000 rounds through it?

I was asking what 'use' would you have for this information ?

Satisfaction of curiosity

I was just pulling your leg alittle

0,5-1 million shots?
Well, first of all it would be cone area. Hot gases destroy metal surface and cone area looks like pores and corrosion one.
Regarding chokes - yea, there will be some minor constriction changes, but first of all because of the same corrosion just before chokes, if we talk about carbon steel. You can clean barrels after every shot, but this corrosion will be there any way.
Thats why you need honing.

This is strange, because some ATA shooters, in another time, have claimed to have shot hundreds of thousands of shots from their guns and their bores are just fine. This business about enlarged chokes from normal use is an old wives tale in my opinion.

The quality of steel used in the barrels has greatly improved in the last 150 years. I suppose that could make a difference. I just read a Doublegun Journal article that stated an English cartridge company shot a million rounds through a Boss and the bores only increased 0.001" or one thousandth. I don't know which Doublegun but it was one of the first four.

I know Humpty asked about the choke and what I read was about the bore.

Best,

Mike

If you assume that the chokes are going to erode (I'm not sure I buy it, given today's plastic shot cups, but...), isn't it logical to assume that the bores would erode also (altho perhaps to a lesser degree?). If so, then the choke deterioration would be less.
