I shoot a 6 pound 4 ounce Sauer ten gauge with wall thickness no less than mid thirties. There are many tricks that gunmakers use to lighten guns. I agree with a poster who correctly modifies my opinion to state that .024 up in the north end of a barrel is no big deal. I just wouldn't like it in the hands on section of a Damascus barrel.

Interesting thought. Has anyone seen any evidence of erosion of the holes of a heavily-shot ported gun?

Big D, My Browning Citori Trapgun has 67702+ counted rounds through it.
41244 through the top barrel and 26458 through the bottom. No signs of errosion.
The plastic and carbon that collects in the ports probably acts as a protection?
And the gun has not had one mechanical failure I might add.
A modern day "Old Reliable"? :duck: :)

I have several ported guns - and one I have shot at trap for several decades. There is no sign of anything.

By the way - "Porting" and "Pitting" are TWO entirely DIFFERENT issues. Ports do NOT constrain pressure, but rather deflect pressure to the advantage of the shooter. Pitting tries to CONSTRAIN - but given PRESSURE - could erupt the barrel when pressure is at it's peak - i.e. and n.b. - which is not the the advantage of the shooter, should he/she be missing a few fingers when the pressure is more than than the barrel wall thickness might provide...

Porting and pitting - again - are two very different issues with two totally two different effects and outcomes.

John, you have brought "pitting" to a whole new high. In the future, when I buy a pitted Parker, I will drill those little buggers out to relieve the pressure. Is this a great forum, or what?

Hi Bill,

Not to take the topic off topic, but I think someone said "pitting" is like "porting"...? Which - well - isn't exactly right..

Should I just delete my post?

;)

Best to you!

John

And oh - yes... I forgot to add... Please do drill those pits out... It will make the barrel lighter too...

:shock:

I love this forum... So much to learn and do....???

Best to ya'!

John

Blame me for the porting entry. I realize that porting ain't pitting, and probably should have started a new thread, but the porting picture triggered my small brain. It occured to me that that hot gas venting thru those small holes over time might create havoc. Sorry for the diversion

No, John, please don't delete your post. It adds some technical aspects to the voodoo of barrel pitting.

As long as you don't delete yours? Not sure about any "technical aspects" about pitting that I might have added - but - if you say so, it must, well, be true?

Gawd - I love this forum... So many are so right over so much - and all at the same time..!! Who would have guessed???
