No idea what a TPS wad is. Have you checked Ballistic Products archives? Tons of 12 & 10 gauge loads.
TPS,..Tungsten Propulsion Series of wads. Looks pretty much identical to their MultiMetal wads (whish BPI has discontinued
), but made for HeviShot/ITX.
BPI did have a HeviShot loading manual, but they have dropped that also, in favor of their ITX shot.
Yes, I have gone through their archived "load of the week". Found a couple different HeviShot loads, but not what I was looking for.
