BTW does anyone have any pressure data from Gamebore. I corresponded with the Canadian division this past Spring and couldn't get anything out if them.
The world cries out for such: he is needed & needed badly- the man who can carry a message to Garcia

Brian, if wholesale won't order for you, my smith will. We were talking about combining on some orders a while ago and I just haven't done anything yet. Let me know if you run into any problems with wholesale and I'll get a combined order in. I will do.

I have just been thru this problem. 65mm is not 2 1/2 in. It is about 2 5/8 which is about what most ammo is . 2 1/2 inch is 63.5 mm. I just ordered some 2 1/2 empties from Ballistic and to my frustration they are not 2 1/2 but marked 65mm. In my short chambered 12 ga gun they would hardly chamber. I called and complained about it and unfortunately they did not seem to understand the difference. As usual, I would not worry about shooting a "2 3/4 " in a 65 mm gun as it is close enough and likely the same chamber.

I personally wouldn't stuff long cartridges into it. There is a big difference in the proof pressure test for 2 1/2" chambers and the longer 2 3/4" ones with such a narrow bore. The standard load for these 2 1/2" ones is only 9/16th. ounce of shot whereas the 2 3/4" stuff can have up to 1 ounce. A bit like firing 12 bore 2 3/4" magnums in a 2 1/2" chambered game gun. All the British cartridge makers and all the European ones, as far as I can see, make ammo for the 2 1/2" 28 bore. Lagopus.....

I'm not sure when 2 3/4" became standard for the 28. Reading Miller's post, my initial thought was that we were already there by the 50's--but maybe not. My 1940 Shooters Bible shows 28ga shells available in both 2 7/8" and 2 1/2". No 2 3/4" at that time.

The first Parker 28's were short chambered.

I have short chambered, lightweight 28s. They recoil heavily with factory loads. My Francotte weighs 4 3/4 pounds. I load regular 2 3/4" hulls with light shot loads with a bean or two to take up the extra space. I don't change the powder charge or wad. The lighter shot load lowers the pressure enough that I don't worry about the length of the shell. However, the idea about having a skeet shooter bring you some RSTs is a good one.

Here in the UK Gamebore sell their 28 bore,16gm in both plastic and fibre wad in a 65mm case with No 6 or 7 shot.
Their 19gm (No 6 & 7), 25gm (No 5 & 6) and 28gm (No 5) come in a 70mm case.
Not sure if this is any help.
John
