It appears that the 22 ammo ice jam is finally breaking this Spring.   I have seen it starting to show up on some gun shop shelves in limited quantity--though mostly sporting grade stuff so far rather than match quality. 
 However I recently ordered some of the new Norma stuff from ChampionShootersSupply to test. 
Yesterday I got the following notice from them that I thought I'd share:

Hello friends, 

Champion Shooters Supply has just received shipments of Norma Match, RWS Target Rifle and Rifle Match and Eley Target and Club. A link to our ammo page is at the bottom of this email.

We also have special selection RWS R50 in stock. This is very special R50 which went through testing in addition to regular R50 tests, prior to its selection, and now we are bringing it to you. Previously, this R50 was extremely rare outside of Germany. Now you can get it here. 

Norma TAC is coming soon and Norma Match is a very welcomed surprise. At $7.50/box and $700/case, it is outshooting Eley March (black box) at twice the price. We have solid, trusted reports from around the country about Norma "Match" ammunition consistency and precision. Most everyone who has tried Norma "Match" has purchased more - it is that good.

SK, Wolf and Lapua shipments are 7 to 14 days out so stay tuned for more updates. 

Anschutz 1712 silhouette sporters are still on sale for $1895 each. We have a few left. 

Again, thanks for your time. Todd W.

I'm posting this as a friendly service to my fellow rimfire match shooters. 
 While I have had very good service from this dealer, other ones may do just as well and may also have the same ammo in stock now. 
Likewise I do not specifically endorse the ammo mentioned above---after all "your rifle may vary"    good luck and better shooting.   DWS

Big Reno gun show this weekend has ammunition dealers with full range of ammunition and primers.  Prices coming down each show. getting rather reasonable at this time.  So good I will have to increase my range time.....
