Have 2 P Mullin 8 Ga Doulbles with 4 1/4 in chambers with
Cannon breeches-(reinforced for 6 inches then quickly tapers to nornal 8 ga size). Have info from Greener's "THE GUN" about
8 ga guns with 3 3/4 in chambers-nothing longer. Any knowledge
about 4 1/4 in? Any written info?
Both 40 in Jones Underlevers -one 15 1/4 lbs , other 17 3/4 lb
the later with 2 1/2 lbs of lead in butt.
Also P Mullin 10 ga Cannon Breech 4 in chamber?
Thanks
