Researcher,

Do you have a pic comparing the breeches of the twelve ga. guns? Also pics to compare the muzzles of the three, 12 heavy, 12 light, 16. It appears that the breech end is same as the 16 with the chambers rebored to 12 ga. by comparing the wall thickness. Very interesting addition to the RBL story. Do you know how it shoots yet?

I have a light 16 RBL that is my go to hunting gun now. I would like to try a heavy hulk 12 ga. for trap and maybe waterfowl. I am interested in why you don't care for the heavy gun. What did you intend to use it for, if I may?
