Howdy folks. After a long time looking, I've acquired a 16b Sterlingworth with 30-in. barrels. It's all original, including the 2 1/2-in. chambers. I know RST and Polywad offer 1-oz. 2 1/2-in. 16's, but I have a few flats of B&P 1 1/16-oz 2 5/8-in. loads. Reckon it's OK to use these in this gun, or should I wait until I have the 2 1/2-in. loads in hand? Thanks.
