Al Bandle, of Cincinnati, on Christmas Day defeated the famous shot, Captain A. H. Bogardus, by killing 100 live birds straight to the Captain's equally remarkable record of 95.
Bogardus shot a 12-gauge L.C. Smith gun, hammerless, 7 lbs. 12 oz. weight and shot
4 drams American Wood powder in his first barrel, 1 1/4 oz. No. 8 shot in first and 1 1/4 oz. No. 7 in second, backed up with 3 1/4 drams Laflin and Rand Orange Lightning powder.
Bandle shot the same make of gun, 10 gauge, and used, first barrel,
4 drams Wood powder, second, 4 drams Laflin and Rand “F.F.F. extra” powder, No. 7 shot.
DuPont purchased Laflin & Rand in 1902. L&R “Orange Extra” Black Powder was still offered in the 1927 Hercules Sporting Powders booklet.
