Feb 24, 1900 Sporting Life The Winchester people offer the Repeater in 10, 12, 16 and 20 gauges, loaded with any of the standard brand of nitro powders; the maximum loads for this shell being 10-gauge, 3 1/2 drams powder, 1 1/4 oz. shot (shell boxes list 28 grains Ballistite or Laflin & Rand Bulk Powder); 12 gauge, 3 drams (DuPont Bulk) powder, 1 1/8 oz. shot.
We know 12g 1 1/4 oz. 3 1/2 Dr. Eq. BULK Smokeless was about 11,750 psi; DENSE Smokeless was 12,600 psi. 10g would certainly be less.
