A Poor Man's 50

[gunsofliberty]

This is what I'm thinking of doing: I have a Martini Action that I woul like to attach a 50 caliber barrel to make a 50/90. I can get ahold of a 50 BMG barrel to attach to the action. Now in this twist, which is one in fifteen, is this too fast for the gun or am I going to have to buy a custom barrel at one and twenty-four twist? I would like some input from anybody out there, becuase what i want is to make a long range rifle.
Will be shooting both black powder and smokeless powder.
Now here's some of the other calibers I was thinking of making:
-45/120
-45/110
Now with the 45 calibers, will i get the extra punch and knock down power that i have with the fifty?
Thanks for reading and helping. :-)

Make sure your cartridge will make it around the corner and into the chamber. I doubt a 45X3.25 will. 50X2.4 probably will depending on the bullet but make sure.

1:15 is probably too fast for best accuracy with BP and cast boolits. Check out Green Mountain. They have the proper blanks and they're not expensive.

What are you going to do for sights?

How about target weight? A long range 50 is going to be using 700+ grain bullets. Gonna kick some.

Stock design? Will it be comfortable to sit behind or will it beat you up?

All things to think about, as well as many others.

A poor man's .50 is a contradiction in terms.

I have shot 850gr boolits out of a 1-15" twist gun, from 1200fps to 2200fps with good accuracy. You could go 50AK or 500NE too.
I have a 50AK Pedersoli sharps clone. It gives a good kick with heavy boolits

The poor man's 50 would most likely be the 50-70. It uses less powder and a lighter bullet than those powder chomping monsters. And it is still a 50 caliber! I got into the 50-70 cheap but after building the rifle, things got expensive fast!

[hickstick_10]

Have you ever shot or loaded for the calibers you express interest in? Theres nothing cheap about the brass, lead or powder they consume. I doubt the 45-120 will turn the corner to make it into a martini.

50-70 if you must, its an excellent shell, but consider a 45-70 for your first. Twist in the barrel is not all that matters, groves do as well, I have a single shot 54 caliber breech loader that uses an old machine gun barrel, the results are workable, but not the best.

i do lot of black power shooting ,40/65,45/70,and 56 cal long range bp and lot of smokeless to

An old shooting buddy just finished barreling an MH to .44-77 Sharps because .45-90s (as he loads them) were too long to chamber.

Just in terms of lead that is a correct statement.

Guns,

I have a large framed martini rebarrel project; I bought a new 35" Walther-Lothar barrel with a 1:48" twist and chambered for 577Snider.

With this 2" case there is no problem fitting to the loading shute and with a plain base boolit of 615gns it will hold 90gns of black.

With a new cut chamber you can make cases from 24ga solid brass shotshells.

This "Super-Snider" is a truely awesome round in the strong Martini Action.[smilie=p:

"Super Snider" indeed. Wow! The next question is how will you stock it so it doesn't replicate a Mule's kick?

[gunsofliberty]

New walnut stock with full length forewood and brass Snider butt.

I shoot a big 50 with a 650gn boolit and 105gn FG so it can't be more recoil than that! :groner:

The 45-70 is never a mistake.

[Kenny Wasserburger]

Again as mentioned the length of the 110 cartridge wont fit through the Martini. A 45-90 often won't.

45-70.

The true poor mans 50 is the 500 s&w Handyrifle. Mine is a real hoot and has never fired a factory round. For less than $400 I got gun, brass, powder, primers, lead pot, WW's, dies and molds. For peanuts I can put together a load that will blow a half inch hole in a pigs nose out through his curly little piggy tail.
