i don't understand why the rifle manufacturers (hopefully savage with hornady making the ammo) start reintroducing the 5mm rimfire. interest in that caliber really picked up a few months back with centurion making the ammo. with the success of the "new" .17, and all the odd ball centerfires introduced almost on a weekly basis, why would it be such a gamble?
i would think with today's manufacturing processes, and doing some research on how the 5mm rimfire performed in the past, i would think that if reintroduced it would blow away the 22 mag and 17hmr and probably would become be the #1 choice for hunting, and possibly target as well.
it's characteristics are between the .17 and .22 mag, so it would pick up on the 17's shortcomings (dealing with wind and being a bit of a light bullet), and the .22 mags shortcomings (being not as flat shooting as the .17). so you'ld essentially have a flat shooter with the bullet weight that would be the best of both worlds.
now i never shot one of the 5mm remingtons, or personally know of someone that has one i could "test", however i think it would be an accurate all around use shouldered cartridge.
i know if savage came out with a bolt for it and hornady came out with the ammo tomorrow, i would be on the list instantly for it to be under the christmas tree.
...that's what i like about toe tags; one size fits all...
