Mark, looking at a Alliant Powder booklet that was in a Mec 600 Jr. Mark V that I just bought, it lists 2 loads using Federal Plastic w/paper base wad:
Green Dot 29.5 grs. 1 1/4 oz shot, CCI 209M, Rem. SP10 1265 fps @8,300 psi.
Green Dot 29.0 grs. 1 1/4 oz shot, Win. 209, Rem. SP10, 1265 fps @8,800 psi.
Remington SP Shell
Green Dot 28.5 grs. 1 1/4 oz shot, CCI 209M, Rem. SP10, 1265 fps @8,800 psi.
Green Dot 29.0 grs. 1 1/4 oz shot, Win. 209, REm. SP10, 1265 fps @8,800 psi.
Unique 31 grs. same componants as Green dot, CCI 209M, 1265 fps @7,500 psi.
Change to a Win. 209 everything else the same, 7,600 psi.
All these reloads are for 3 1/2" hulls, the funny thing is that it seems kind of odd about the left over room in the hull.
On the Alliant Powder web site, under 10 ga. lists the same loads but it tells you to see note. Well the note is to put in anywhere from 4-6 .135 cards in the bottom of the wad to fill the hull.
So using a hull cut to 2 7/8" following the receipes, don't add the .135 cards.
This is only my opinion, plus you might have to roll-crimp the hull or possibly wilth only 1 1/4 oz. it might 6-8 crimp.
Red Dot wasn't listed for any of the loads in 10 ga.
Good luck and let us know how you make out.
The 8,800 psi is getting away from low-pressure but the other ones should be good.
