.25WCF Martini is in hand

The current line of thought in schuetzen and ASSRA is to chamber the 25-20 in a faster twist barrel, usually 1-10, then use cast bullets weighing anywhere from 100 to 120 grains. This would be used at 200 yards, which I’m sure you know.

There is enough powder capacity to hit velocities between 1200 and 1600 fps, so you have room to experiment with various speeds for your different cast bullets. I’ve seen both spitzer and round nose profiles used.

I sort of doubt your Martini is barreled in this fashion, but I would certainly determine the rate of twist just to be certain. Breech seating a long, skinny slug like that would be pretty difficult, due to both your scope height and the slightly peculiar manner in which the Martini accepts ammunition.
