21 Sharp ammo

nice but dunno that the uptake in the firearms community is going to be huge as there are many tiny calibers already

 

[Scevaph]

isn't that special. Companies can't keep ammo on the shelves and they are bringing out new ones.

 

[Belt Fed]

Nope, file this one with the 30 super carry.

I would say it has the same challenges as one would in introducing a new deer rifle cartridge. We have enough already, not that there isn't room for improvement but at some point we got this.

I watched this last night on NRA TV show. It would have been better if it could be used in current .22 rifles.

How long before someone tries a 22LR round in one of these rifles or this ammo in 22LR firearm?

My guess is that it will fire in a .22 L.R. but at .010 - .012 undersized the accuracy would be pretty bad and vice verse a .22 LR fired in one would swage down the lead bullet without a stutter but again not so good accuracy. I see the chamber pressure on both is 24,000 PSI. I am sure the folks at Winchester have done this already with no ill effects or they would not have made the case / chamber essentially the same.

Nope, A lot, and I mean a LOT of folks in states that have rifle cartridge restrictions these two have flourished. I don't know many people that still hunt with shotgun slugs, they have went with those two rounds to hunt deer.

In restricted states that used to require only shotgun slugs these cartridges are quite capable and popular. I love my 350 legend. Would I use it if I could use my 308… No.

You posted this as I was typing.

No thank you.

This. I fail to see what it does that a .22 LR, a .22 WMR, or one of the .17 rimfires can’t do equally well without the need for new firearms. Hard pass for me

From a 09/18/2024 American Rifleman article-

"While the .21 Sharp will chamber in a .22 LR rifle barrel, due to its sub-caliber projectile, it cannot be fired with any degree of accuracy or precision. Additionally, .22 LR cartridges will not fit into a .21 Sharp chamber due to its heeled projectile. All that should be necessary for most .22 Long Rifle-chambered firearms to shoot the new cartridge is a .21 Sharp barrel. "

Next cartridge to slowly fade into obscurity.

There are like 20billion 22 lr and various 22 caliber cartridges rimfire and center and firearms to shoot them out there. Most makers make at least once of the above.

Play taps sooner rather than later.
