Chris,
ITX is harder to load for our older guns because the ITX maker, Ballistics Products believed in high velocity. That philosophy usually mean higher pressure.
The load below is from BPI, at 10500 PSI which is only 500 PSI below the SAAMI maximum working pressure! You better make sure your old gun's barrels have
plenty of wall thickness!
BPI L0AD#100907-2465-4/2/BB
HULL: FEDERAL 10ga. 2-7/8” (2.85”)

I have bought ITX but use it a little. Most of mine sits on the shelf because Nice Shot is so lethal and so much easier to load!
My favorite load for the Short Ten is:
HULL: *FEDERAL 10ga. *2-7/8” (2.85”) * *
PRIMER: FED209A*
PROPELLANT: Longshot 33.0 Grains*
WAD: *SP-10
SHOT: *1-3/8 oz
Nice Shot*
BUFFER: *Mica*
ROLL CRIMP: *For over shot card use a COS12 or a N710 card. *
Result:
PSI 8780 FPS 1335
There is also a new non-toxic American E-Shot

E-Shot looks good but I haven't tried it yet.
