I have a left hand 592M and 17 boxes of ammo. (maybe more, i'm still looking :>)) ?)
I bought it new many many years ago, and IMHO it kills better than a 22 Win Mag. and also seems to be better than the 17HMR although i've not shot a ton of stuff with the 17 like i have the 5mm and 22 WMR.
"If" ever the time was right for the 5mm Rem. mag. it's NOW!!!
I also wish they would make a huge batch of 5mm ammo, but if they do i sure hope they keep exactly the same bullet they used before!!!! I've always felt the 5mm did such a "great job" because of the bullet design.
