My brother inherited an older 10gauge shotgun that requires the older 2-7/8" shells. They seem almost impossible to acquire these days. So what I would like to know is if anyone knows if it would be possible to empty out the newer 3-1/2" shells to make the shorter shells. If so does any one know of a book that contains recipes for 2-7/8" 10ga shells?
 
Is it modern enough to be good for smokeless? Many older 10 gauge where only designed for black powder pressure.
There are many books that will contain that data but I would guess that, by far, the vast majority of it will be for brass shotshells.
A quick Google search came up with a bunch of results of people cutting down 3-1/2" hulls to use in older guns. Have to use a roll crimp though.
It seems everyone is using SR7625 for their 10ga loads and it's been discontinued this year by Hodgdon :-(
There are some specialty ammo companies in the US that load bismuth shot in that length for use in older guns with barrels that can't handle steel shot. Good luck finding any in Canada though.
 
Ya, I found a place in Europe selling the shells I need but they're not cheap. I'm going to have a gunsmith look it over before I try anything. This is just for the novelty of shooting it. I wouldn't want to reload a ton of them. Plus i think I'd have to do it by hand because I cant find a press that'll do 10ga either. I have access to a lathe so I'm going to try to find dimensions or a 10gauge roll crimper or reverse engineer a 12ga one if I have to. Might have to make a punch for OSC's too.
 
RST in Pennsylvania makes 10 gauge 2 7/8 cartridges. I believe they load nice shot in some of their loads too. Call Clay at Prophet River, and see if he can get some for you.
 
MEC makes 10ga presses but I have no idea if they can do 2-7/8" or not.
Even if it can't crimp the shells you'll probably have to use a roll crimp for 2-7/8" anyway so you'll take the shells out before the last step anyway.
 
You might try the following:

"Reloading for the Short Ten Gauge" ... the most complete available on loading for the short 10 ga, including how to convert a 10 ga. - 3-1/2" MEC Steelmaster
to load shorter lengths. Includes 46 different tested loads for 10 ga. ... 2-5/8" and 2-7/8".
