I met a person once who used to load real short 12 gauge shells in both plastic and paper hulls. These shells were like 1 1/2" long and were more of a novelty. I think that they were loaded with 1/2 - 3/4 oz. of shot.
He told me that he loaded them on an old fashion Lee Loader that had its barrel cut down.
I am guessing that he used the old nitro over powder card wad and felt spacer wads.
I think that you could have probably loaded 12 or more into an unplugged Model 12.
Recipes ... Hodgdon has a bunch, but, when you get your wads figured out, you can use standard 2¾" data.
If your friend has old guns, and even damascus, you might want to stay with SR7625.
As far as loading kinks, you can either buy a 'short kit' from PR, MEC directly, BPI, etc, or, depending on how many you'll be loading, glue 3 nickles together and put under the shell at pre-crimp & final crimp station. Or PR has some machined brass spacers in their misc. MEC accessories.
A 'magic' wad for 2½" is the Gulandi 1217 and 1219. Both PR and Grafs have them.
I load only straight-wall hulls, so I can't help you if you want to load RemChester.
I have some good Bismuth loads if he wants to hunt waterfowl, too.
The guy has a bunch of 2-1/2" once fired hulls he was wanting me to try and reload. If I already have the right size hull why would I need the trimmer? He also told me that all of the hulls were bought over in england! dont know what kind of problem that will cause.
2 1/2 inch chamber is standard on many Engklisg game guns. I load short shells on a Mev with a spacer kit and just trim them with a shell unloader but you could use any kind of razor blade or as pipe cutter would do. I like to Roll crimp mine so I never mix them up. The shells are fun to shoot and at times serve a purpose. Jeff
I hear you. I have never had any hulls that were 2 1/2 inches too start with. I find that when I shorten the hulls and try and make new crimps they wind up looking like crap. I have had several different crimp starters over the years and have had some decent success but never the way a factory shell looks.
I think he would be better off just shortening his own cases as then all he would have to buy is a roll crimp instead of a short kit as well. Jeff
Here was my first stab at it (really this was the second, crushed the first one) Cut this gun club down, and loaded it with 17.4 grains of clays, and a cb1100 wad, using 1 oz. of #8/#9 shot (dumped a little out so it is a little shy of 1 oz.) crimp was not to bad. Used washers for spacers and just used my Mec jr. Good thing he doesn't want to many of these because going back to a single stage loader after loading on a progressive Sucks!
I finally found out what shells he has They are Wesley richards 2-1/2". He has a bunch of hulls that he wants me to try and reload. He also shoots a Wesly Richards 12 ga. Does anybody have any good recipes for these shells.
