Anybody ever test to see what affect shooting a 2.5" shell in a 2.75" chamber has on the pattern compared to shooting a regular 2.75" shell of the same size shot and essentially same powder charge in the same barrel?  |

| I would suspect it would be similar to shooting a 2 3/4 in a 3 " Chamber. Not to much so fars as I can tell., |

| You will hardly see, feel, smell or taste any difference. Keep in mind that the only reason for the 2.75" hull was to be able to use the new fold crimp machinery back in the day. The extra 1/4" of hull is simply what is needed to fold crimp a finished hull. Everything else remained the same as far as components were concerned. |

The Winter 2001 Double Gun Journal has the article by Sherman Bell called "Finding Out for Myself" Part V "Long Shells in Short Chambers".
After extensive testing carried out in a very professional manner he concludes:
"With loads that are sensible in a light 2 1/2 inch gun, we see no dangerous pressure levels produced. I see no reason, related to safety, to modify an original 2 1/2 inch chambered gun to shoot 2 3/4 shells, If The 2 3/4 Inch Load You Intend To Use Would Develop Pressure That Is Safe In That Gun, When Fired In A Standard Chamber!
I personally perceive slightly greater recoil with my 2 9/16" chambered 16g LC than with my 2 3/4" chambered 16g LC using the same 2 1/2" shells, and for that reason the brls are with Dan Lammers getting the chambers lengthened right now. |

Personally, I shoot 2 3/4 inch 12 gauge ammo in my 65MM 12 gauge guns
but I do load 2 1/2 ammo for my 16 gauge guns
And I do shoot 2 3/4 ammo in my short chambered 20 gauge guns.
These are LIGHT loads.

| Does anyone have a copy of that issue of the double gun journal? I have been trying to find that article on the internet just so I could read through it, but can't seem to find it. If someone has it and could e-mail me a copy that would be great. Thanks- Matt |

Thanks for the fast and informative response guys!
I am lookig at buying a flat of the 2.5" shells for dove season and am planning reloading the empties for my 16 ga that is has a 2.75" chamber. So looks like I am good to go! |

Wrong!! The 2 3/4 inch shells began coming into regular use long before the folded "pie" crimp was introduced. Both Remington/Peters and Winchester/Western introduced the folded "pie" crimp on their target loads in the late 1930s. WW-II delayed the introduction in hunting loads until around 1948.
When the first progressive burning powder loads, Western Cartridge Co.'s Super-X were introduced in 1922, they came in Western's 2 3/4 inch 12- and 20-gauge Field shell. When the 16-gauge was added to the offerings later that year it came in a 2 9/16 inch Field shell.
While longer 16-gauge shells were offered all along, the 2 3/4 inch 16-gauge shell really took off when Remington Arms Co., Inc. introduced their Model 11 and the "Sportsman" autoloaders in 16-gauge with a 2 3/4 inch chamber in 1931. While the regular Remington Nitro Express 16-gauge shell was put up in a 2 9/16 inch case with a load of 3 drams equiv. and 1 1/8 ounce of shot, they introduced a 2 3/4 inch 16-gauge shell with a load of 3 1/4 drams equiv. and the 1 1/8 ounce of shot and called it the Auto-Express.

The Western Cartridge Co. "Super-Seal Crimp" first appears on their Xpert Super-Trap and Expert Super-Skeet loads in the Western Ammunition Handbook (6th Edition), which discusses the many championships won with them in 1939. At that time they had added the cup over the basewad, but were still using the "Seal-Tite" fiber wad over the powder. By 1948 they had added the "Super-Seal Cup Wad" over the powder as well, and in 1948 the Super-X and some Expert hunting loads got the folded crip as well. As far as I know Western never went to the folded "Super-Seal Crimp" on their 2 9/16 inch 16-gauge shells
All the Remington shotshells are shown in the 1938 catalogue with the roll crimp, but the 1939 Remington Trap and Skeet Equipment Catalog shows their Remington and Peters skeet and trap loads with the new folded crimp. |

You could certainly shoot 2 1/2 inch shells in a Remington Sportsman, but why? Those guns were built for SAAMI Spec. 2 3/4 inch shells from the get go. |
