Willkommen zu unserer doppelten Schrotflintenwelt.

I'd rather shoot the shit with oLe jOe than yourself, no harm intended of course
jOe ain't stupid..he can be a bit blunt, but its not a bad thing,cut to the chase kinda stuff
you go on way to loooooong
I like jOes instant & curt ,prolly accurate estimates too
Godamm, I Dig jOe
Just my opinion

I think Destry has a better idea.

I was always under the assumption that high volume shooting actually leaves lead and plastic biuld up in the bores and choke. Can there be biuld up and wear at the same time?

Thank you very much, gentlemen! It is always a pleasure to be here.

Joe Wood - Thank you very much for your kind words I'm already fine, just can't go to work yet

HomelessjOe I know and I was pulling back don't give up so early next time

Now let's see if I got it straight.

There doesn't seem to be a definite "yes" or "no" answer to the question, apparently, it could happen as an exception, but not much likely to occur with a modern gun as a rule. If it does happen to a modern gun, it's justified to suspect a factory defect or operator error as the likely cause.

Here is a case study that provides some indication of wear so that can be expected due to normal use.
The gun in question is a Charles Boswell live pigeon or duck gun. The barrels are steel it has 2 2/4 chambers and is nitro proof for 1 1/4 ozs.I have owned and shot this gun for 30 years approx. During this time I have fired between 20,000-25000 rounds[all lead shot] mostly at trap.When I aquired this gun the proof diameter and muzzle diameter of the barrels was measured with an Egerton-Chubb dial indicator bore gauge,set to precision masters.The dimensions were recorded as is my standard practice. I have just re measured the bore and choke dimensions; here are my observations.
Right Barrel
Proof dia. .732 Muzzle .695- At time of aquisition.
.733 " .696 Present diameter
Wear [.001] [.001]
Left Barrel also shows .001 wear at the proof diameter but.002 wear at the muzzle.This almost certainley due to my predominate use of the left barrel when shooting singles at trap.From these changes in dimension, one can approximate that it would take 200,000-250,0000 rounds of lead shot before the barrels would have worn to an out of proof condition.During the same period of time the wear on the left barrel choke, would have reduced it from full to half choke.

I don't get it. Why write a post in German to a man who is Russian?

I am 1/4 Russian, I lived in Germany for a year or so, and I shoot British guns. Speak to me in Ebonics only, please.

Humpty Dumpy's question on wear is legitimate and poses interesting questions. jOe, being jOe is stirring the poo again and really should be ignored. I find it very irritating when some supercilous twit puts up a post in a foreign language just to prove how fucking marvellous he is. I can do that as well, but choose not to do that as there is absolutely no point, in my view. Totsiens, mes amis,

I have a 3200 Remington that's about 35 years old now. I haven't kept track and I won't say it has been shot a lot, but it has been shot steadily over the years. The inside of the barrels have a black finish which I have to presume is just a very thorough blue job. There's not the first sign of that finish wearing through to bright steel. How is that? My take is that shotgun barrels don't wear much, chokes either.
