If you put them beside a 2 3/4" shell, they are shorter. We have a short chambered A5 that shoots them well, and won't shoot anything else.


Update. Shot 3 shells of the Remington thru the Ithaca (2 3/4" chamber), brought them home, and put them next to std 2 3/4" hull. They are DEF shorter! And they WILL cycle thru the Mdl 12 after firing! After I got done mic'ing everything, the "std 2 3/4" (only one hull) mic'd out to 2 23/32" fired. The Remington mic'd out to 2 21/32". The 21/32" is short enough to cycle in the Mdl 12.

Before I fire a bunch of them and break the original stock again (which will make it firewood) I an going to have the forcing cone lengthened if it is not 2 21/32" long. That way I will know I am not going to get any over pressure and the shorter std Rem hull will cycle.
