Re: 1912 20 gauge chamber length
Hunter Arms Company lengthened the 20 gauge chambers from 2 1/2" to 2 3/4" in 1936. If bored longer at the factory, it will be marked on the barrel flats
Please carefully measure the chamber length, and if not now
2 1/2" it is critical that the end of the chamber wall thickness be measured.
