Howdy folks. First, thanks to all who participated in the "Help needed on pressures of modern loads" thread. I've followed it daily and learned a great deal. Thank you. Now here's my question for all you Sterlingworth afficianados. I have two 16's, both Philadelphia guns: ser. no. 350xxx has 26-in. bbls, and ser. no. 364xxx has 30-in. bbls. #364xxx has short chambers, which is what I'd expect. #350 has 2 3/4-in. chambers, and 2 3/4 is stamped on the barrel flats. Reckon it left the factory with 2 3/4-in. chambers? How often do you see that? Thanks. JK
