This morning I was reading an old copy of Rifle that included a review of the 5mm. The original ammo exceeded specs by over 50fps and the downrange energy exceeded the mag a bit. I think the availability of the mag in revolvers plus the difficulty of handling the 5mm pressure (similar to the .17WSM) in ordinary rimfire actions killed that nice little round. We'll see how the new kid fares. With a good stash of brass and a bunch of cute little bullets, I'm sticking with my Hornet. If I was banging out a few hundred rounds a day at pdogs, I'd probably be singing a different tune.
