Re: 450-400 Jeffery in a Martini?

The action will most certianly 'handle' it, but I think it's too short for that particular round.

The large Martini has very successfully been re-barreled (fast twist) and chambered to the .444 Marlin, and operating at close to 50,000PSI+. The ballistics I remember from the 70's era Gun Digest were 400gr. in the 1,950fps range - from that shorted, straightened out, rimmed '06 case.

Would I do that - possibly - but shows the normal .450/400 is well below the working range of the action.
