So is there anything stopping enterprising ammo manufacturers from developing a rimfire round to the same specs and ballistics as existing NATO rounds? I'm thinking unlimited mags in the AR15/AR10 and M14 etc. :)
Sure you couldn't reload it, but it would still be a **** load of fun. Million dollar idea right there :)
Sales would be retarded here, beta c's for everybody!
 
As I understand it, you would need so much power to crimp a rimfire cartridge of that power, that it's not feasible--which is why the move was made to centerfire cartridges in the first place.

Hopeful someone here can provide a more complete answer--or one that corrects me if I'm way off.
 
The only problem I see is that our market is so limited, it wouldn't be worth it to R+D such a thing. It would never pay for itself. Also, I'm thinking the firearm would have to be altered from it's centerfire state, to strike the rim of the cartridge.

Furthermore, the powers that be would probably find a way to restrict/prohibit it's sale if it became popular.
 
Part of the problem is in the manfacturing, one of the reasons they switched to centerfire was that priming a larger case is costlier/more hazardous, so the went to Berdan priming (pain in the butt for us reloaders), and Boxer priming (the one we use). There has been several larger rimfire cartridges in the past and they are no longer made for these and many other reasons.
 
I have been thinking a lot about this as well.

To my mind we need to fight to get the crap gun control laws changed instead of trying to find the ways around them.

However, I would be VERY interested to see more semi auto gun chambered in 22mag that is kinda a middle ground to me, it is more power than a .22 and still falls under our stupid regs meaning we can have unlimited capacity for rifles, and short barrels as long as the overall length is 26"

The limiting factor for 22mag seems to be mag design.

Ultimately we need gun control overhauled in Canada resulting in gun laws more like New Zealond, I think that would move us closer to US style freedom but still appease the Canadian need to control or micro manage gun ownership. While I am all for total firearm freedom I don't see that happening, I do think we could model a country like NZ and maybe get some rights back. It'd be a start at least.
 
The limit with rimfire cases is the strength of the case. To light off the priming compound, the rim has to be maleable enough to deform, but strong enough to contain the pressure.
 
Flipside, make a centerfire cartridge to the same specs as 22lr so it can be limited to 5. Not.

Honestly, your best bet would be convince a manufacturer to do to the traditional bolt action hunting rifle what Armalite did to the semiauto rifle. It's a good idea, imagine being able to pick a receiver and then drop in a barrel, install a magazine adaptor, drop in a trigger, decide what controls you want, and pop on a stock on a bolt action rifle. I for one would love it, being able to use the same platform to train in 22, then swap out some parts for larger calibers when competition/hunting season rolls around. If I ever get to wear the daddy pants in a machine shop that's what we're developing and I don't care how much it costs. You could even make it fit current rails and foregrips and stocks, and I don't see why it woudn't be able to use some other parts as well. If it happens to use mags that are compatible with the AR platform, so much the better. Of course, the RCMP is pretty much guaranteed to prohibit any manually operated gun that uses mags that work in ARs, but it's nice to dream of having such synchronicity.
Honestly right now boltguns are generally very dated designs, and very proprietary. A modular update is what they need to kick them into this century.
 
The NFA recently approached the government about repealing magazine capacity limits. I believe this restriction is the catalyst to your idea. MAKE SOME NOISE and support the NFA to your local MP. Support of this idea!

Always gotta be careful with this s**t -- I would think that any govt would carefully weigh the potential political capital available from the _two_ ways of solving this inconsistancy. Hint: we might not like what they decide...

Mag cap limits are always the first thing that comes up after these mass murder incidents, maybe because it's something that is easy for the public to comprehend, and I suspect LE is solidly behind them too, for whatever silly reasons. There's other battles I'd rather see fought frankly.

I do like hitzy's idea though...

They would be rimmed cases which means the rim would be thick and hard to make. They would also have to redesign the firearm to take and fire the cartage which would mean redesiging the bolt and hammer ect because it all has to move over.

The reason rimfire rounds went away was because the bigger they're the bigger spring you need to fire them because they become thicker. You would also make ammo expensive because it can't be reloaded ect.
