LC Smith 10ga fine damascus Syracuse era. Bores measure .790/.792, I believed honed. Wall at 3" L-.177, R-.168, at 9" L-.082, R- .086; Min. wall near muzzle before chokes L-.038, R- .046, Chokes .033/.035. 2 7/8" chambers. Plan on reloads in the 5000psi range? Safe to shoot?

Providing there's no crater-like pits remaining, I'd have no qualms whatsoever, in shooting it with ~ 5000 psi loads---I'm assuming the MWT anywhere along the entire length of the barrels doesn't fall below .020 and no crease, dent removal or other repairs have had to have been made to the barrels.

Craig, in your email, you asked about bore size from factory, and I said I believe it was .775 even for the Syracuse L.c. Smiths. I know the Fulton ones were and I had seen a print of the bores and most were +.000 - .002. That goes for all of the L.C. Smiths. In most of the 12 ga. that I have measured all hammerless were .727-.732. The hammer guns, some were as low as .724 but none higher than .729.
As I stated on the site, beware of any of these old guns with "shiny mirror" bores, you can almost bet they were honed out.
I would have them measured again, just to be sure, and to give you peace of mind. Plus I would buy a set of Gage Mates down to 12 ga. and get even lower psi loads.
Good luck and let us know how you make out here and on the LC Smith site.

Go for it! I have been using one of Sherman Bell's 1 ounce loads in my 1893 vintage (one iron twist barrels) Baker 10 with outstanding results. I load 22 grains of Hodgdon's Clays, an SP10 wad and an ounce of 7-1/2 shot. A 1/2" thick 16 gauge felt wad, along with a 1/8" 16 gauge card wad, brings the shot right up to the perfect spot for a rolled crimp. The barrels are choked full and full and throw some tight patterns well beyond 40 yards. This load is in the 5000 PSI range. I am loading 2-7/8" shells for the Baker, but will use the same charge in my 2-5/8" Parker. Good luck, and enjoy that 10!

I would think a larger bore would make for a little less pressure.

Craig, I forgot to add, the thinnest wall readings would be around 12-15". The 9" readings are good and I would check out the 12"-15" range also.

No pits remaining, the thinnest measurement anywhere is .038 (just before the chokes), no repairs or dents.

BP working pressures were about 9,000. You should be safe well above 5 k psi.

I shoot a damascus barreled 10ga. BAKER, using low pressure 12 ga. reloads (#7625) with gauge-mate chamber inserts. Works fine for me.
Shooting 12 gauge hulls in a 10 ga. reduces the peak pressure somewhat.
