I had a old LeFever G grade 12- 30" Twist barrels and I bought a box of British BP paper 12- their No. 6 shot 2.5" 1 0z. after we Magnafluxed the barrels, we shot it for proof and pattern with some of those loads, also some 2.5" RST shells as well- absolutely no problems with either- I still have some of those paper BP12's and also some in 20 bore (3/4 oz. No. 7 shot) and I agree, it is fun to use them in one tube when hunting with others-
I bought a older 1851 Colt Navy .36 cap and ball- with some accessories in the box- and perhaps you BP gents can identify and date same for me- (1) Older ed metal can with screw off top with logo label DUPONT 1F Superfine FFg Gunpowder with Wilmington, DEL. U.S.A. address (no zip code) on back in black ink-- at base MADE IN U. S. A. below that NET Wt. 1 lb. or 454 Grams= after I have my gunsmith check over this older Colt, wonder if that powder would be correct for that weapon and cal.- I also found in the box a new red and white same size cannister of GOEX, INC. also FFg Superfine Black Rifle powder- later issue as it has a zip code for the factory in MOOSIC, PENNSYLVANIA, 18507, U.S.A.- similar powders? just the "Uncle Dupey" stuff is older, right??
I only reload AA 12 target hulls- with Red Dot and 209 primers and white wads-for clays and non-game birds- have no experience reloading paper shells with BP-thanks for any information on the powder cans--
