89 grains?

Yes, and what Paul says is true. Still, beyond what he says, very few of us have the equipment to accurately measure the bores beyond the muzzle. So we don't really know what the bores are past the choke, and we should be aware that Pedersoli has made changes in their bore diameters over time. I would guess .705 to .715 (an educated guess but a guess all the same). Personally, I would want real information before taking off metal (not before discussing but before taking off metal).

Remove the barrels and look at the breech area. Italian/European guns are stamped with their gauge, but it's done in metric, at 25.4 mm to the inch. A 12 gauge tube will be stamped 18,3 (they use a comma instead of a decimal), which means 18.3 mm. That translates to 18.3/25.4 = .72045", close enough to standard 12 gauge. If the gun is stamped 18,3 but measures less than .720" at the muzzle then it has some choke.

Paul, what you say is true about the wad problem, when I got the gun I recieved a supply of 12 ga wads and a supply of 14 ga wads. it does make loading a chore. from my gsmith days a moderen 12 ga will be bored app .727 cyl bore, mod at .715 and full at .700 plus or minus 1 to 2 thousands. so I was very supprised to get a .675 muzzle reading. this turkey and trap model was expressly made for users wanting or needing a very tight choked gun for their style of hunting or shooting. the sucker does shoot tight groups like all tight shooting you must aim crefully or you will miss that old gobblers head, aint much for close up squirrels either yours houndog

new pedersoli dbl 12 ga stamped "89 grains bp only", "1/14 oz shot" on the barrel, is this the max charge they reccomend? what if i go over? id think a gun that costs as much as these would be made of good enuf quility to not burst with borderline max loads but maybe not??? thanks Scott.

I'm neither a metalurgist nor a lawyer, but I can contribute this from long experience using Navy Arms (Pieta) 12 ga SxS:

My standard, most accurate "heavy" load is 80 grains of 2f under 1 1/4 oz of shot. More often I use 1 1/8 oz over 70 grains or 1 oz over 60 grains.

That's cuzz these guns are LIGHT, and heavier loads boot like hell. I have zero inclination to use anything heavier, and even with cylinder bore and no chokes, they make very decent 30 yard guns with that 1 1/4 oz load.

Good enuff for me, and to heck with the lawyering and theorizing. They're not welcome on my hunts where all this stuff really matters.

I'm with Brown bear on this--couldn't have said it better.
