Dave, just out of curiosity, what is the barrel length of your Fauneta gun? Someone told me they usually had short barrels of around 24 or 25 inches. Also, have you tried conventional saboted slugs on it?

Barrels are metric approx English number is 27.75" (70cm). I have not shot it with anything yet....As soon as it comes back cleaned up (inside) we start our experimentation.

Gents, I do have a 20 bore Paradox mould with a hollow point if it helps. I paid through the nose for it. I would think you might be able to get the rifle to shoot with it, but it will not be easy and the results will not duplicate the 1500 FPS. John

Another question....It was suggested that in addition to the "paradox" type bullet I try round balls in the gun. What should the size of the ball be in relation to the rifled portion of the choke? Should the balls be cast soft or hard?

I don't see why you can't get the 1500FPS load with good pressure. You just need a slow powder that won't smoke the cases. I have had good luck with IMR 4759 not 4756 in myn 12 gauge. I use 64.0 gr of IMR 4759 behind a 615gr hollow base for 1555FPS. I can't give you a starting load for the 20, but Tom Armbrust can. He teted my load at 11,400PSI and 1555FPS average. Do not use H110 or 296 as they can hang fire, and explode! I was trying AA #9, but didn't have great luck with it. Ballpowders will give you more power than the slow flake type powders for the slugs. Try double base powders, and call Tom Armbrust to discuss your loads. He can be reached at 815-385-0037. Good luck Greg S

I have never heard that. If you read the Fosberry patent, the differnece between bore a choke is about .040. Generally, you should shoot a thousandth or so less than the bore size.The bullet should be no harder than 15:1. Remeber that there are at least five variables to play with, crimping, bullet depth, powder, lead hardness and wadding. Good luck!

Hello Dave. If you can mic the bore at the chokes I may have something that works for you. You will probably need a sizer die, but they are good to have anyway.

Here are my measurements...
Right Bore: .633 Choke: .60375 Groove: .62125 Left: Bore .6325 Choke: .6045 Groove: .6225
I have a few friends in the model shop at work so a simple push through sizing die is not a problem...

You mentioned the round ball and this is something that may work It should be self explanitory. The driving bands are approximately .625 but there should be more than enough to size down. Tom
