David, my 1882 Remington has the 2 3/4" chamber. Don't think there were many at that length.

A Vintager friend of mine was chatting with Morris I think at the Vintage cup last month . Anyway he told me Morris told him that he had a couple tons of whatever this new powder is coming as we speak !

He also implied to me Morris planned to use the new powder the same as I use SR7625 , by that I mean in most all moderate loads for the 10 , 12 , 16 , 20 and possibly 28 gauge .

If what was implied to me is correct and this new powder becomes available I see myself switching over to it once my supply of SR7625 runs out .

What is the name of this "new" powder?

I shot 100 reloaded RST (federal) shells at the southern side by side and all seemed fine. They were loaded with 31.5 gr 7625 and 1 1/8 #8 shot. 1044 wad with 1 , felt 1/2 in 16 ga wad in the shot cup and a 6 point crimp. Carvel

Carvel

What kind of press did you use to get the crimp ?

William

press for short ten
 

William, I use a Mec single stage for the short 10. I use a Ballistic Products metal crimp starter and it gives the crimp folds very good definition.I have used roll crimps before but the case life is too short with roll crimps...at least for me they are. Jim

Dunno , everything I was told I put in the post above .

William, I use a mec 600 jr with the short kit and the brass crimp starter. Works great. Carvel

Components together start loading soon. Have two lots of new primed Cheddite hulls that I will trim back to 2 7/8 then Roll Crimp. Follow the advice posted, add a filler wad bottom of the shot cup. 1 1/8 of 7 1/2 Red dot or Unique from the spreadsheet. Looking for about 1150 fps

Also have a fair amount of RST empties Cheddite hulls 2 7/8 inches that were fold crimped. Folds don't roll all that well, best if they are trimmed back to fresh plastic then roll the crimp in. Case will end up about 2 1/2. That what I do with 20's and 12's cut the crimp away, fired case is a bit shorter than 2 1/2 inches depending on the hull brand. Not a problem use appropriate wad for the light shot loads I am using. Those gauges use the rolled shells for spreaders makes it simple to identify

10's components not as easy, Remington wads hold a lot more shot than the 1 1/8 I plan on loading. All advice is to add a filler. I cut one of the wads petals back about 3/16 inch, shortened it holds 1 1/8 oz nice and makes a good fit in the shorter cut back case.

Anybody cut the wad shorter to suit the case size ? I would do it for spreader loads only and to use up the fired RST's Seems OK thought I would ask first.

Further to my short 10 post. Loaded up a dummy this afternoon. Cut the 2 7/8 inch RST empty down to 2 1/2 inches removed all trace of the crimp. Threw 19.4 of Red Dot then seated the Remington SP 10 wad on top of the powder.

Dropped a 28 G nitro card wad in the bottom of the Remington wad threw 1 1/8 oz #7 1/2. on top. Still not full to the wads top or enough to fill the 2 1/2 inch case. Added a 12 G Nitro card on top then roll crimped. Nice crimp, shake no noise and the shell finished at 2 1/4 inches

I guess my basic question is which way to go

Fill the wad with nitro cards to make up the stack. 16 G will fill better than 28's, and use a fairly thick overshot or Polywad spreader disk. Or cut the Hull and Wad even shorter. I don't want to use over about 19 of Red Dot or 1 1/8 shot. Pattern is probably the only way to tell. However thought there might be some advice out there.

PS I could go to Unique about 30 grs and up the shot charge to 1 1/4 that will probably make a higher stack in the hull. However have very little Unique and don't need 1 1/4 oz for clay targets
