    When were 2 1/2 inch chambered guns popular? Who manufactured them? Why did they lose favor with shooters? Is anyone currently making them? No big deal here, subject interests me, and I would enjoy hearing your comments. Thanks, Ken

    It gets even more bizzare than this, I have an A-5 Belgium Browning in 16 gauge that is chambered for 2 9/16" shells. I also found a box of 'Wards Best' 2 9/16" 16 gauge shells. The gun works just fine with modern 2 3/4" loads.

    flincher, I would be cautious about leading anyone to believe it is OK to shoot 2 3/4" shell out of a 2 1/2" chambered gun. The angle and length of the forcing cone affect the pressure. Guns vary considerably in that regard.

    Prior to the development of 2 3/4" shells in the late 1890's, the standard chamber lengths for most American guns were:

    20 ga. 2 1/2"
    16 ga. 2 9/16"
    12 GA. 2 5/8"

    The transition to 2 3/4" chambers didn't happen all at once. The 97 Win. 12 ga. had 2 3/4" chambers but the early Model 12 Win. 20 ga. guns had 2 1/2" chambers. By around 1920 or so, most manufacturers had switched over to the 2 3/4" length.

    I have an LC Smith chambered for 2 1/2" shells. Kicks like hell with 2 3/4" It is not shot anymore and I have not looked for 2 1/2" shells to test it. There are no chamber markings on the barrel. A chamber gauge from Brownell was used to determine the length. Like the poster above stated - do not recommend folks use the longer shells. Would you shoot a 3 1/2" shell in a 2 3/4" chamber? It is rather doubtful so what is the difference. Stick to what the design calls for. Tractor tires on motorcycles look weird and do not handle well.

    I have a model 12 Win. 20 ga made in 1912 with the 2 1/2 " chamber. would like to shoot it but the shells are not cheap, so it's a safe Queen. Butch H

    OK,you gotta figure the chamber length takes the OPENED shell into account right? 2-3/4" chamber for a loaded shell of 2-1/4". Allows 1/2" for the crimp when it opens. So a 2-1/2" shell shoud be 2" long loaded.

    What in the hell is this little green bugger? As you can see in the pic it measures 1-3/4" loaded. Guess you would call it a 2-1/4" shell.

    Jim, it's the only 2" one I have on the shell board I built. It does stand out. Most people that see the board want to know what that little green one is. 137 shells on the board and that one jumps out at them. Then they ask what in the hell that big red one is.

    I came across a few 8ga. Win. industrial shells a while back.

    flincher100, your saying that you had a factory marked 28 ga. with 2 7/8" chamber. I take it you no longer have it but do you know who does?

    Butch H, I have a 1921 Mod 12 in 16ga 2 9/16"chamber. I plan to get it rechambered to 2 3/4". I know these two offer this service, Williams Gunsight Co, and Simmons Guns. They ream the chamber, lenghten both the forcing cone and ejection port. Cost was somewhere around $200.00 if I remember correctly. J.Woolsey

    Thanks for the info, Do you think it will hurt the value? It being a 1912 year gun I would wonder if it would be better off in someones collection?
    Thanks again for the info. Butch H

    A friend of mine yeears ago shot his 2 9/16 chambered shotgun al the time. He cut once fired hulls to the correct length and adjsuted his Mec loader down to load them. Seems to me a better choice than messing up a possible collectors item. JMHO Bill

    Pat, thanks for the heads up. After reading some of the comments, I may just get me a Mec and load my own 2-1/2's. My 1921 is pristine, and it would be a shame to cobble it up. J.Woolsey

    I have a 1916 Model 12 in 20 gage with 2 1/2 inch chamber with a solid rib and is 25 inches long. It's a nice original gun no rust or pits but blotchy from age and the wood is excellent. This is the correct specs as Winchester 20 gages were all 2 1/2 up til 1930 I do not recall when barrel length changed but originally they were 25 inches. I decieded not to have the chamber lenghtened just keep it original would sell it for $750.00

    Jim; Now you are going to get people thinking that all buckeyes fudge a little. I do appreciate you telling us the secret to your success and I have ordered several bags of the copper 4's for caps and copper 6's for 16s for the upcoming season. Thanks again.

    Don
