I wonder if anyone has the chamber dimensions for Longrange or Wild Fowl guns. I don't see them in the books. I thought that because 2.75 chambers are listed as ending at .792 diameter when the forcing cone begins, the 3.0 inch chamber would end at the same diameter. So, I made a plug gauge .792 diameter by 3.0 inches long. It doesn't go in the full 3.0 inches in either of my long range guns. Also, It appears that the chambers on the FW models are about 1/16 inch shorter than 2.75. What's up with that?
