The Martini-Henry .577/450

“OK, the Snider was fun. Let’s shoot that Martini-Rossi.”

“Martini & Rossi is a booze brand, dumbass. The rifle is a Martini-Henry.”

“Er … right.”

OK, I’m not saying that actually happened. But I will admit that historic rifles are not really my thing. Fortunately, my BBTI buddies are more knowledgeable.

The Martini-Henry was the single-shot, breech-loading rifle that succeeded the Snider-Enfield (initially in 1871; our rifle was stamped 1887). Designed from the start to shoot a metallic cartridge, it was quicker to load and fire, faster to reload, and more powerful than the Snider-Enfield. It shot a bottleneck cartridge based on the earlier .577 Snider-Enfield, known as the .577/450, which had a 480gr soft lead bullet of .450 diameter (hence the name) pushed to about 1350fps, for about 1900ft/lbs of energy (about 400ft/lbs more than the Snider-Enfield). Because of the increased velocity/energy and the better ballistic coefficient, it had an effective range out to 1800 yards (for ‘volley fire’ applications).

The Martini-Henry is overall a slimmer, more manageable gun than the Snider-Enfield. It’s about 5″ shorter overall, with a 33″ barrel, and weighs about the same.

The biggest design improvement was that the action functioned by the use of a lever. Pull the lever down, and the block drops down, allowing a feeding ramp to align with the chamber. Insert a cartridge, close the lever, and the block rises and the gun is ready to fire. Here are some images of it:

Preparing to load.

And here’s the rifle being fired:

 

That’s with the full-power, traditional .577/450 loads. Which, while they’re black powder substitute (and hence a ‘rolling’ impulse), still have quite a bit of recoil.

However, there are cartridge adapters available which allow you to use common .45 Colt ammunition. It’s just a brass (or steel) sleeve with the shape of the .577/450 cartridge into which you insert a .45 Colt round. Here’s a brief clip showing that:

 

And here’s what it’s like to shoot the rifle with the adapter:

 

Much less recoil. And if you’re buying commercial ammo, much less cost.

Shooting the Martini-Henry is easy, and while there is a noticeable amount of recoil with the full .577/450 loads, it’s not bad at all. With the adapter and .45 Colt loads, the recoil is very mild. Hickock45 has a nice “woods walk” with a Martini-Henry of the same vintage here:

Definitely, if you get a chance to shoot one of these rifles, take advantage of it.
