doublegunshop.com - home Forums General Discussion Double Rifles, Paradox Guns & Gauge Rifles @ doublegunshop.com Paradox cartridge question

I seem to be unable to find any real data on the Paradox cartridges, specifically 12 and 20 bore. The bullet data is not to hard to find but load data seems to be sketchy.

Are the chamber pressures of the Paradox cartridges in the same range as their shotshell cousins? Is there a published source for loading or are folks using slug data?

Thanks.

Found the thread finally. Searching the wrong terms.

Spoke too soon. Not much in the thread.

Ross Seyfried has written some very informative articles in Double Gun Journal and Handloader Magazine. I believe he has a go-to load using Unique with which he is very happy.

Do you happen to know which issue it was or how I can find out. I would like to purchase it as a back issue.

Just an FYI:
I know of 3 shooters who have blown up rifles in the past 12 months. 2 LUCKY ones shooting vintage rifles with modern propellants and 1 shooting a Savage ML (designed for smokeless) with smokeless and lost a hand.
We are fortunate in the USA to have many Black Powder options available to test vintage rifles with.

Dave, did you pick up a Paradox or Explora? One is sort of on my bucket list but I fear the necessary funds will continue to be more rare than the guns. I read the same Seyfried articles but can't tell you which issue.

Neither at this point. Actually it is still sitting on a sale rack minding its own business. I can't tell you for sure because I didn't look much past the tag and kind of a once over. I know the Expora was developed for a different bullet than the Paradox but past that I am kind of sketchy. Both were ball/shot guns IIRC. I have seen some BP loading for the Paradox but even that is somewhat confusing, especially when the listing from WR are approaching 9 drams.

a quick once over on 12 bore paradox guns. All use aprox a 730 gr bullet. The standard H&H load is 1050 fps, explora and magnum H&H load 1200-1250fps, Super magnum explora 1500fps. I owned a super magnum explora for a while. Brutal recoil.......

Brutal I am not into. My .72 DR with 780 grain conicals is more than enough. 730 at about 1050 sounds like it is in the same general class. Is there a modern loading that can safely duplicate that? I have been referred to a back issue of the DGJ but they can be scarce and I don't know which one to start with.
Fortunately Paradox moulds are not hard to come by, at least new manufacture.
