More help with 10ga Peder Cyl/Imp Cyl brrls

[mnbearbaiter]

I know I've beaten it to death, but it's been a long time? I've shot alot of game with my SxS Pedersoli. I use ffg T7 cuz I am a long way from true black so I run what I can get? I've noticed less powder and heavier than recommended shot charges seem to do the trick as well? Especially for turkeys which I just harvested with the old girl. My main issue is that the left brrl shoots left and the right shoots right at the 10-25yds I prefer? I seem to remember a poster on here talking bout "filing", or taking down the the brrls from the inside to the outside with a file or diamond hone which would force pattern inwards??? Is that really a thing? Is this gun supposed to be centered a 40yds with each brrl like some fine English dbl brrl shotgun? Any help regarding this firearm I'd appreciate and sorry I've been away so long without a post?

By "filing" brrls I meant the end of them tapered from inside to outside. Not actually inside the bore, but the end of the muzzles themselves if memory serves me correct???

You'd need to do that to more than just the end of the barrel. I few inches deep would have to be honed on one side. The pressure escapes and pushes the charge away from it.

I discussed it a bit in this thread: SxS round ball shooting

I can try to talk you through it if you need more info

A well made double gun is regulated to a specific range. IE: The barrels are adjusted in a jig so that both balls, or both shot patterns hit the same point at the desired distance. The barrels are then permanently joined. Soldered, brazed, or these days maybe epoxied. Then the rib is added. There are some good smiths who could redo that process so that the gun is regulated to your preferred range, but it would be expensive. Likely more than the cost of a new Pedersoli.
Given that you know where your gun shoots at your preferred range, why not some Kentucky windage?

That's what I've been doing. On flying birds I have no problem tossing a tad more/less lead on em. Standing stuff like turkey i literally hold the stacked beads right out in front of their head brrl dependent. Is this what others do? POI to POA improve at longer ranges so I assume beyond the 30yd mark (farthest I've ever patterned it) it would be true?

For me I don't like messing with filing or deforming the barrels to move point of the pattern center. I just know where my pattern is the densest and use "Kentucky windage" .
