Looks as if original proof was for the 2" shell with 3/8 oz of shot. Has been re-proofed @ 65mm, approx 2 9/16".
It's really immaterial though, anyone who has been following this board for about the last week should be fully aware a gun weighing only 4 lb 3 oz & with a side lever opener is total Junk, not worth carrying home.
I will have to admit though "IF" I could find one of that weight I could afford I would be greatly tempted even though I am absolutely NOT a .410 fan.
If, as so many say, a gun has to weigh at least 6 lbs for me to be able to hit anything with it, it may as well be a 20 or 16.
