You can shoot both a 2 1/2 and a 3 inch shell.
The shell length that the chamber can handle should be stamped on the barrell.
Thompson Center Contender
No made for 2and a half inch shells
No it does not. The Browning BPS Hunter is a shotgun. The "410" signifies the shell size (guage) in this case .410
The presently manufactured Taurus "Judge" in its many variations fits that bill in .410.
You need to talk to a gunsmith
if the shell is 410 but 2 1/2 inches long no problem if you a 3 inch chamber size
No. While there ARE firearms made to fire both the .45 Colt and the .410 shotshell, they were made for that purpose. Never attempt to fire ammo that a firearm was not made to fire.
Yes the stated length is maximum so if it says 3" you can also use 2.5 and 2"
Yes, you can shoot 2 1/2,2 3/4, and 3 inch shot gun shell in that barrel.
Depends on the guage and length of the shell, and the size of shot used. It may be as few as 3, (.410 Buckshot) or as many as several hundred (10 g birdshot).
