Sleeving a Martini Henry Rifle Barrel

[vykkagur]

O.K., just a thought. What is the barrel shank diameter of the Martini-Henry vs the barrel shank diameter of a Lee-Enfield? It was common practice to leave a nub of the existing barrel of a Remington rolling block in the receiver, and thread it to take the smaller shank of a new barrel. You may be able to do that with your Martin-Henry. You could then bore out the remaining length of Martini Henry barrel and slide it over the un-reduced Lee-Enfield barrel, as a shroud (without the negative connotation).

Absolutely agree, except I wouldn't waste my time with any sleeving. Finish the cut right through, face off the stub ahead of the polygon, then bore out and thread it. Forget about Lee-Enfield barrels; get a plain .303 blank. Turn and thread the end to match the stub, trimming the threaded length to match the headspace of the original barrel. Inlet for the extractor. Profile the blank to match the original barrel, then cut and crown to length. Transfer the sights. Done. You now have a modern steel .303 barrel, but outwardly matching the original .577/450. Contrary to a lot of stupid old wives' tales that litter the internet, stub adapters are a perfectly safe practice, if properly done. I've used them myself for years.
