Interesting: only 89 of the 10 bore Paradox were made by H&H, of those only 37 were hammerless like this one.

Like Roscoe's screenshot, I will be using Track of the Wolf thin case brass, and a proper 875 grain Fosbery Paradox bullet sized .806" and cast of 1-20. Initial loads will be 220 grains (8 Drams) of Swiss 1 1/2.
I expect the recoil and smoke will be about on par with my 15 1/2 lb 8 bore G.E. Lewis?

I'm waiting for a push thru bullet sizer made by my friend Steve Bertram to get the bullets down to size, the original H&H mould (not numbered to the gun) casts a bit oversize and slightly out of round.
As this one was Nitro Proof I will eventually try Cal Pappas' recommended smokeless loads using his Blue Dot recipe.

I will have to do a "family group photo" of my bore rifles 12, 10, and 8
Sorry but a 4 bore remains out of my reach unless I score a big lottery win……..
