Instead of trying fill in with solder between the ribs, Tom and taking the chance of getting too much heat there (barrel separation), I'd simply use JB compound. Leave a little bubble of epoxy sticking out and file it flush after it cures. If you want to file out a piece of aluminum or steel to fit and epoxy that in, that's a possibility as well.
If this shows I'm a 'hack' well, that wouldn't be far off.

Thanks Daryl I hadn't though of that I may just leve it as is for now if I find a very good load that shoots well in both barrels I but not together it will be easer to reregulate with a wage. By the way the barrels are no longer tuching their is about a 32nd of an inch beween them so not as much convergents as with the longer barrels.

Shotgun barrels are noted as having more elevation in the rib due to larger base compared to muzzle diameters (Lt. James Forsyth 1860) and more conversion of the muzzles due to getting the shot loads to print together at close ranges. Both of characteristics are negatives when shooting slugs. Shortening the tubes helps reduce both potential problems. I filled my rib with JB and it worked well and still hasn't shot loose, the current owner now having used it for his moose yearly, since about 1988.

From photobucket copy the 2nd addy of the 4 and paste it in the box for images at this site.

Tom- in 10 bore, you will be at the same point I was with my 12 double. I started with heavy, highest velocity shot loads and went from there, keping an eye on pressure - case feel, action opening, primer appearance, wads loosening, that sort of thing.

I don't have the exact weight on #4 buck - maybe someone else can help. I think it's 22gr. - but not sure. I will use that weight as I think it's close.

The loading I am looking at in Lyman's book is in 3 1/2" Remington SP Express w/composite base wad, WW 209 primer + 41 #4's (902gr.): wad column = Power piston - + shot and 46.0gr. Blue Dot for 1,336fps - listed at 10,000LUP.

Considering a 10 bore round ball in pure lead weighs 200gr. lighter than the buck load at 700gr., about 650gr. in WW alloy, I'd start with the above load.

Some of the other powders & loads with merit delivering decent speeds to start in 10 bore are:

:Fed case - WW209 - 40.0gr. SR4756 - RP piston + .125" card - 15 # 00 buck - about 750gr. total at 1,283fps @ 9,500LUP

:same case - 45.0gr. Blue Dot - same wad and shot - 1,263fps at 8,800LUP.

:Rem Case - WW209 - 38.0gr. SR 4756 - Piston wad - 14 00buck- about 700gr. - 1,268fps @ 9,200LUP

:same case - WW209 - 43.0gr. HS6 - Piston wad - 14 00buck - about 700gr. @ 1,311fps - 9,600LUP.

Hope this helps you get started.

Daryl thanks I will keep them saved and use them to start with round ball loads.
