Re: .410 bore Paradox, rifle choked or Explora barrels

A question. Have .410 barrels ever been made into paradox style rifled muzzles?




I doubt it, but it would make neat SxS rifle, just the same.
With 1/2 ounce bullets (220gr.) it could likely make 1,500fps. This would be slightly more powerful than a long barreled .41 Rem Mag.
Pigs, deer, goats - whatever. I think it would be fun, but regulation might be hit or miss - mostly miss unless it was only one barrel that was rifled.

Using another barrel as a guide, I think something around 16" to 18" rate of twist would be about right.
The rifling might be from .010" to .015" deep in a full choked .410 bore barrel which should grab the slug.
Would need a fairly long bench for both shotgun barrels and guide barrel held in vices, however the "stroke" to cut the grooves would be short, likely only 5" to 6" long at most.
Enough for the cutter to clear the muzzle for cleaning chips(mud) and re-lubricating. Best to use the breach area in front of the chamber of the guide barrel, to prevent any enlargement of the bore at the muzzle.
Lead laps would have to be case on the guide rod running through the guide barrel and into the .410's choke area which would have the cutter inset. Deepening the cutter's contact would be done with slips of cigarette paper under the cutter in it's housing in the lead plug.
A long rod would be needed for the rifling guide, 48" would suffice easily, but depends on the guide barrel length.
