I'd say the only thing it'd be good for is game about rabbit sized-coyote. In my opinion 17hmr can take care of just about anything from a squirrel to a coyote with the right load. I think the 5mm rem is just a caliber that is pretty useless since the 17hmr is a popular varmint round for all varmint and predator hunters alike. 5mm is 20 cal, and 204 ruger pretty much kind of fills that niche in the gap there. Of course, because I am who I am, I'd buy a 5mm rem just to have it to shoot out at the range, but it would be cool to see a 39, or an 1894 chambered in it.

Happy for all the people with 5 mag rifles they can stock up on ammo now but I'll stick with the .22 mag the wide variety of bullets and loads available for it now specially the 33 grain pointy bullet killed any desire I had for a .17, would like to see the 33grain polymer tipped bullet in a hot .22 long rifle load jist fer kicks

I don't even believe the 17HMR will be with us long. The wind blows that little bullet right off the target at longer ranges.

No malice intended but again you display your youth. At your age you would have little or no first hand experience with the 5mm so I can forgive you that.

The 5mm Remington Rimfire Magnum was, and is, the most powerful rimfire of all time. Not the flattest shooting, but the most powerful. The current load has a 30 grain bullet that has been repeatedly clocked in excess of 2400 ft/sec @ 68 degrees from a 24" barrel.

The ballistic coeffecient of that 204 bullet is .120 so the ballistics look like this.

With a MV of 2400 and sighted in a tad under 1" high at 100 yards.

Energy at 15 ft. : 384 foot pounds
At 100 yards: 212 ft pounds
At 150 yards: 154 ft pounds
At 200 yards: 113 ft pounds

At 125 yards the bullet hits about dead on.
At 150 yards the bullet hits -1.7"
At 200 yards the bullet hits -8.4"

I has a similar trajectory to the 17HMR and stomps it cold in the power department.

Your analogy of the 5mm being useless because of the 204 Ruger is foolish and narrow minded. The same could be said for your highly vaunted 17HMR being worthless due to the 17 Fireball or 17 Remington centerfire cartridges. Different uses, eh?

Have you ever shot a coyote with the HMR?? I'm guessing not because it is a p--s poor coyote round. In fact, I find is marginal for 125 yard prairiedogs and prefer the 22 magnum for that. To shoot a coyote with the HMR would be cruel. I know! You probably know someone who has done it, but it's just too little cartridge.

As to the 5mm being put out by Marlin. Maybe in the 1884 or the NEF but not in their standard rimfire action without some severe design modifications. The original 5mm operated at 36K pressure (VS 21-25K for the 17HMR and such) and while the Centurion round is less, it is still outside the structural parameters of the Marlin bolt guns.

Fred,
You would be very unhappy with it. It be stubby and wouldn't open up reliably. Look at CCI's 30 grain WMR polymer tipped round; there are expansion issues at 2200 ft/sec!

If you want hot in a RF. Try CCI Velocitor (40 grain at 1420) Aguila Inteceptor (40 grain at 1490) or Aguila Super Maximum (30 grain at 1750). I only have one rifle that likes the Super Maximum at all, but the other two scream from most of my .22's. I will admit, a prairiedog hit with either of the last two gets really messy! ~Andrew

I own a couple of dozen .22's and only one, my 1954 Brno, shoots the Super Maximum well and this only with the bullet redesign three years ago. (before that it was shotgun patterns) My Brno will shoot them into 3/4" at 25M which isn't great but acceptable. Oddly, the gun that Centurion Ordnance tests all their .22 ammo with is a SAKO Finn Fire and that rifle will shoot it into a quarter inch 25M. I have been after them to to a change in the nose profile in the hopes of increasing accuracy.

I would much rather shoot the Interceptor 40 grain. Shoots as well or better than Velocitor but at much faster speeds. I got 1497 at 15 feet which would correct to over 1500 at the muzzle from a 24" barrel. My 880 SQ loves the stuff! ~Andrew

I have gone over the specs at rimfirecentral and posted them there,believe me the 5mm is a round head and shoulders over any other rimfire.It shoots a projectile of 38 gr. faster and flatter than the .22 WMR 40 gr.[I am a WMR lover} it is nearly or more than twice the weight of any 17 HMR .It packs a wollop and is a great round.Will they chamber one in a Marlin I hope so and I'm sure they will if it catches on but there is a catch- it works at 37,000 psi so needs a kind of special action ,I don't remember what Marlins bolt actions are able to handle but a Semi-Auto needs a delayed blowback action so a new gun might be needed.Shootrj2003

Remington made it orginally, so with our new step parent in control of Marlin. The marlin .22 mag was on the 94 action and the 5mm would surely fit that bill. Have you looked into the conversion to centerfire for the 5mm's? If you could find a 94 in .22 mag and commit blasphemy and make it into a 5mm centerfire or rimfire, that would be a handy shooter.

Find a .218 bee and rebarrel to a 5mm wildcat?
