Greener-Martini in 45/70 strength
#284790 - 03/07/16 02:53 AM

I have a Greener-Martini in 45/70. It has an octagon barrel and is in very good condition. I'm not sure who did the conversion but it certainly looks to be a quality job. I've been told Navy Arms but I'm not totally convinced.

I'm wondering how strong the action is and which ammo would be safe to use. I believe it was made in the 70's so it's was meant to use smokeless loads. I suspect I should stay with Springfield Trapdoor loads to be safe but this action seems a lot stronger than any Trapdoor...

Black powder or nitro for black loads.

I'll likely shoot both...I don't think it can be hurt no matter how much black powder I load the 45/70 case with but smokeless is another story.

I'm pretty sure I recall a Navy Arms Martini, in 45-70 and also .444 Marlin, being available back in the 1970s. As I recall it was offered as a target rifle.

Don't quote me but I suspect it's more than capable of shooting any 45-70 ammo you care to run through it.

The Navy Arms Martinis were marked on the barrels, as I recall. Had one, still remember the recoil of Keith's 45-70 load. Damned unpleasant design for hard-kicking loads. Pain of firing might be as good a limiting factor as anything. . . . I never felt I was pushing the limits on pressure with any load I was willing to shoot 5x off the bench! (Unlike the Ruger #3, where I did sometimes wonder.)

Someone--Numrich maybe--offered a conversion kit to 45-70 for the Martinis.

Any load suitable for a Marlin should just fine in the Martinis Navy Arms put out. Seems to me, the NA rifles were Octagon to Round in the Martinis, not straight octagonal, but they made both in the Rolling blocks, so probably in the Martinis as well.

Their other Chambering, as noted above, was .444 Marlin. for pressure levels on the .444- look below.
