In BP's Status of Steel Revision 8.2 They listed 2 7/8 Winchester Fiber Base Wad
Fio Primer 616 Powder HS-6 42.8 Wad BPD10-Tuff Plus 2 1/4 12 ga Wool felt in base of shot cup & thin mylar wrap
1 1/4 Oz of steel
Press 10300 Vel 1410 Temp range 70F to 10F
I have used this load in the past it it performs OK
There were two other short 10s with the fiocchi 10 hulls shortened but as I
remember Fiocchi quit making the hull.
I do have a Beretta single trigger 3 1/2 10 but I like the 2 7/8 gun better for handling.
With 1 1/4 oz bismuth I shoot 30 grains of Long shot in the 2 7/8 Winchester Hull
using BPs gas seal 10x and a SP 10 wad. I usually load it with # 5s. I do not have the data for this load but have it somewhere in my notes that it was tested.
