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.
