For anyone who has one of these rare birds, the Model 591 and 592 rifles (like me)...Aguila has just come out with three new loadings
for the 5mm RRM! Glory, Halleluia!
Aguila had previously issued 30gr. JSP and JHP at 2300fps and 2400fps respectively, in 2009. The original loading was a 38gr JHP Core-Lokt at 2100fps which Remington, naturally, abandoned after a few years. I thought I was dreaming when Aguila re-introduced the 5mm in 2009, so I bought a LOT of both loadings, just in case they decided to follow Remmy's standard marketing lead. Information on their new loadings is linked here: http://www.thefirearmblog.com/blog/2016 ... e-5mm-rrm/
For "those in the know", the 5mm RRM has always been viewed as the best, most accurate modern rimfire round ever developed. On a good day, I can routinely shoot 100-yard, 1/2 MOA, 5-shot groups on paper, and that with a lightweight barrel. Also, its the best and least destructive turkey round I've ever seen, as well. Touch off a 12ga. turkey load at Mr. Tom, and every bird within a quarter-mile radius will hear you. Then, the great pellet-hole search begins on the carcass. No such problem with an easy head or neck shot with the 5mm (at far greater ranges than a shotgun), which will occasionally completely remove the said body parts. The 5mm is no louder than a .22 Mag, and I actually think (without using a sound meter...) it may even be quieter than the .22 Mag. (Sidebar: Why is the .22 Mag such a loud-assed round? You haven't heard loud
until you uncork a .22 Mag in a short-barreled revolver!...
) The 5mm rimfire can also take anything up to coyote, with careful shooting, and the smaller stuff out to 150 yds.
I know the current "hot potatoes" commercially are the various new .17 caliber rimfires, but I've just never been able to bring myself to rely on a pencil-point size slug to do anything other than explode chipmunks.
Since Aguila has shown that they are willing to stick with the 5mm rimfire (unlike its original parent), I'm fairly sure there will be new guns chambered to fire it too. TC has occasionally made special-order Contender barrels since the 2009 re-issue, and Taurus intended to produce a Tracker for it, but never quite got around to it. A reliable supply of ammunition in this caliber should prompt more gun maker interest, I hope.
