Hmmm, I suppose the only couple of things that jump out at me is that Berry's "recommends" 1,200 FPS max velocity for these particular bullets, but I didn't see any trouble going a bit past that. The other notable item is that these slugs do
not have a cannelure on them, and you simply must take care when roll-crimping with this bullet as the plating is
very thin and you do not want to cut through that plating with a too-heavy crimp. (the plating is easy to accidentally slice through when applying too much roll crimp, and when you've done this, the bullet & it's plating tend to come apart.)
2400 is quite flashy and .357 Magnum loads built with 2400 usually throw a rather impressive fireball -- also a trait the Coonan is quite well known for!
