Fyi for those looking for sub-sonic or 22 short. I received this in my email today: Vostok 22 short ammo.
One other thing is Academy has 22 short Remington on occasion. Visit their web site and if you're lucky you may catch it when they have it in stock. Make sure your combined purchase is 39.00 or more and they ship fed-ex to your house for free. I paid 3.99 per box of 50. They're both too high I know but when is the last time you've seen some 22 shorts in a store plus they're real quiet in the 22lr revolver I bought from czechpoint.
