Is it safe to use a duplex load in s muzzle loader?  Thanks Hank45   

I shot muzzle loading slug guns for about 5 years. I tried duplex in it and did well but, my only problem was that the rules didn't allow it so, I wasn't scored.

I can only recommend it in the following type rifle.

1. Modern, crome moly or SS barrel

2. Closed breeching with a screw in insert containing a CF primer and firing pin.

I shot RB muzzle loaders for about 10+ years and know that a lot of the barrels were made with easy cutting steels (11xx & 12xx series) that I wouldn't consider safe with even BP.

Build one as above and I would consider it safe.

Read the warning on the barrel.  Stick to black or equivalent.  That's why the warning's on the barrel.  But like the guy says, their your fingers and eyes.

I've heard of some in the long range muzzle loading community duplexing with some FFFg under the larger grained powder that is the bulk of the load. I suppose they do that for better/quicker ignition. It probably doesn't help to reduce fouling.

Best not read Ned Roberts as a loading manual more than one "tale" good reading not the best information.
