Finally got out to shoot, only loaded 4 for initial test.
8 Drams of Swiss 1 1/2, Fed 215 primer, nitro card and SPG lubed fibre wad, overshot card wad under 875 grain Paradox bullet from vintage H&H mould sized to bore diameter.

25 yards today, standing rest, crossing a bit but can work on that. R1/L1 are 1 1/4", better hold for R2/L2 out of dirty barrels were 5/8"
The 2 "smaller" uppermost holes are from a .577BPE…..

I'm a happy camper. Recoil about as expected, close but not quite as much as my 8 bore GE Lewis with 10 Dram & round ball.

I'd be more than happy with that grouping - well done Mike!

Very nice Paradox. Do you have bore and choke measurements?

Hello gatsby,
Bore is .807”-.808” 5” ahead of the chambers as close as I can measure the slug. Have not measured the actual choke.
Bore has possibly been honed at some time or another as the 10 bore 2/10 proof spec is .803” as far as I can determine from the old sources, and the bores are mirror bright. Unusual for a ~124 year old gun.

ADDED:
I am having Steve Brooks brooksmoulds.com make me an exact copy of the Fosbery HP bullet from the rather worn original H&H mould. Expected to cast out at ~.806” and ~875 grains. The Brooks moulds are some of the best, I have acouple of others to cast copies of proper weight .450 and .500 BPE hollow point bullets and they cast flawless bullets.

I have had more than a couple paradox 10s here
A 920gr bullet and 220gr 2f usually regulates them nicely
Never had any cross.

gatsby, thanks for the input.

Have a 920 grain mould for a solid that I've not loaded up yet as well as the "on order" clone by Brooks moulds of the original H&H 875 grain hollow point…..bore guns seem pretty forgiving of minor variations of charge weight and bullet weight.
After all; heavy 12's, and the 10 & 8 are really "up close & personal" types.

True re bullet weights on these big pdxes but bullet configuration can cause some variation.
The bullets shown buy Curl has been a successfully used configuration in a number of 10 pdxes out to 100 yds.

Years ago I got to shoot a Bland single 4 bore owned by Ray Meyer (I heard that it went to Alaska after Ray's passing)




Well, it's down in south central Montana these days. Drop a line if any of you gents are passing through that area and we'll go shoot.

On another note, I found that a reduced charge(120 grains vs a full charge at 137) of swiss 3F worked like magic in my 5 dram roundball 10, probably because it gives more room for better wads. Shoots to the sights and right at the advertised 1330fps.

Nice rifle too!!!! Those disc set strikers are a work of art.

I often wondered who that Bland 4 Bore went to. Now I know.
For me that experience was a long time ago, I have very fond memories of working with Ray Meyer on the 8 Bore Greener that I had at the time. Getting to fire the Bland was icing on the cake.
