I've been watching Zulu again :good: and been looking at 303 wildcats (again!) and some of the sites recommend Martini Henry as a good choice for a 303 wildcat.

I know the MH was converted to 303 and can handle the pressure of the 303, but how strong is the MH action? I've heard that's been tested up to 60000PSI! :shock:

Does anybody have any references to the action strength of the MH? Just curious, that's all. :D

Thanks in advance.

A few years ago I saw a harpoon gun for sale: the harpoon was about a yard long and must have weighed about 15-20 pounds. The harpoon gun action appeared to be a re-used MkIV M-H action :shock: . No idea what cartridge is used to shift a 15 lb harpoon, or what the chamber pressure must have been like - but obviously the M-H action must have been up to the job....

I've seen those for sale as well - made by WW Greener. As you say if it can something like that, then nothing I'm going to come up with should trouble it. :lol:

I remember viewing a yank gunsmith's webpage who specialised in taking existing martini action rifles and modifying them for some outrageous calibres. I remebered it because he has BSA Int Mk3 modified for a huge hunting calibre.

A bloke in our club insisted on having an old Martini rebarrelled in .50 Action Express because he had a load of ammo, cases and bullets left over from the handgun ban. It took him about 10 years to finally convince a gunsmith to do it for him. Couldn't get the cases to extract except by using a rod down the muzzle end. .50 AE is a rebated rim........ but he was a bit of a cock....
