Polishing Barrell

[Mimosa Gobbler]

I polished the barrell on my Mossy 500 and lead numbers increased greatly but my heavyweight numbers fell off by 50-60 pellet count! Has anyone else had this occur?

Maybe Clark will chime in on this, as he is oneof the most knowledgable on this topic.

Did you also pollish the turkey choke or did you replace it with a IC or MOD before you did it?  Never had a case where a barrel I pollished gave better number with one type of shot over another.  Usually they BOTH improve by at least 10% core density and quite a bit in pattern eveness.

Replaced it with a modified choke!

I followed the instructions at the top of this forum!

I normally "deep clean" my barrels with Hoppe's #9 per the guidelines in the article "Cleaning a Shotgun Barrel" that you can find by clicking on my banner below.

That always improves my patterns and from all the reports I've had from readers, has improved their as well.

It sounds like the change could be as a result the effect on the Flitecontrol Wad of your polished barrel, if I read correctly that you're shooting Heavyweight shot.

I have noted that some barrels shoot that wad (and others) better when slightly fouled.

Here's what I'd recommend. Start by "deep cleaning" your barrel and then shoot a few rounds without cleaning between each shot. You may begin to notice that your patterns improve (regardless of shotshell) before they begin to degrade.

In any case, I'd suspect that shooting a few rounds through it without cleaning may get you back where you were prior to the procedure and hopefully even better.

Thanks,
Clark

Was the H-13 from this year "bought this year"? If so that could be the problem, allot of people are seeing there numbers drop off with this years 3.5" #6's. "me included". It seems that their changing things AGAIN!!!!.

Clark, Thanks I will give that a try!

Check out Clarks site and read up on it carefully. His deep cleaning process works great as does the polishing method mentioned at the top of the forum.
