I have a couple of boxes of Remington .25-20 ammo, old stuff, loaded with 60 grain hollowpoints (Mushroom bullets according to the labelling.) I've fired a few out of one box, the case necks tend to split. I keep them on the shelf with some of the other old ammo/boxes I've acquired. My .25-20 much prefers 75 grain Speer and 86 grain Remington flat points. Even with the high speed 60 grain bullets I don't think a .25-20 is a good choice much past 300 yards.
