45/70 barreled Martini Questions

[delta1]

For those that know more about the Martini action than I.
Will the action of the Martini hold up to full power 70 grn FFG Goex with cast bullets in the 522-555 grains? Rifle has a 45/70 barrel.
regards

Absolutely, if it is in decent shape and the action is tight, the Martini is quite a strong action action compared to the Trapdoor.

I scooped up the Martini in 577 x 2 1/2" Express on the EE last night... Should be a blast to shoot with 120gr of BP.

I have a Martini in 45-70, I've had it for 35 yrs. most loads were IMR 3031 45 grs. with a 330 hp cast lead ( hard lead )bullet
No signs of stress and very long case life.
Extremely accurate rifle.
I have loaded it heavier, but it was not necessary.

My Mark III martini sports a 45/70 bull barrel and it handles factory loads very well.
It also likes cast bullets and can punch a 325 grain bullet out at 1700 fps with no signs of pressure.
One issue with the Martini is to get a Mark III that has a bushed firing pin for 303. This allows higher pressure smokeless powder loads while supporting the primer.
