Speculation Time - Winchester - Worlds Fastest Rimfire Cartridge Coming Soon!

[Eric Mayer]

This is a repost from my Varminter Site:

I was trying to get more information on this, but there is little available. Winchester announced that they are releasing the "world's fastest rimfire", with the announcement coming on January 1, 2013.



From what I was told last week, this will be a NEW caliber and at least one rifle manufacturer has committed to chamber a rifle for it (CZ would be nice, but doubtful).

My guess is either a .20 Caliber (necked down .22 Magnum) with a light bullet, or... a .14 Caliber (doubtful). Since the Centurion 5mm Remington Rimfire Magnum is already pushing their Varmint ammunition at over 2500 feet per second, with a 30 grain bullet, we know that it is definitely doable to surpass the 2550 feet per second that the 17 HMR reaches.

Thoughts, speculation?

I have'nt heard anything on this but, I bet one of my barrel stubbed H&R single shot rifle would make a perfect building platform for whatever the new round might be....

You could be right about a 20 caliber -- maybe they will do it in a non-lead bullet so the 20 caliber runs about 25gr. All they need to do is get an honest 2600fps and it's the fastest commercial rimfire.

this is very exciting, I'm sure we gun-whores will eat it up.

Hopefully the new round will bring about a new action , at least as strong as the old Rem 59x's. This might be the reason no one jump on building a new rifle for the new 5mm. It would be great if the new rifle could be also chambered for the 17HMR, 22 mag and 5mm Mag by switching barrels like Sako and CZ455.

Eric, you get in on all the good stuff... come on now. spill the bean LOl I can’t wait to read more about it!

Gary he can't tell you they're bring out the 18 cal. Hornady has made some in the pass and Lilja has the barrels.

[GLWenzl]

And I have the bullets Ray... looks like another contender barrel !!

[ray h]

Gary I wish I knew at the time that Lilja had barrels and I'd have a gun. I still don't know why they make 18 cal. barrels and no one makes bullets?????

Gary, I guess you didn't see my CZ Scout - 5mm Rimfire - Functioning Prototype thread over on the 5mm Forums? That's good stuff! (not kidding...)
