I think you'll find that most .22 ammo is under 1,200 fps. Not all, but most. Best idea is to visit your local gun shop, see what they have in stock, then read the box. The velocity should be noted on there. Since 22 ammo availability is a little scarce these days, probably best to explore what's available locally unless you want to order some and have it shipped. In simple terms..."standard" velocity usually means it's shooting under the speed of sound. (1,117 fps @ sea level) So, it seems manufacturers want to keep safely under that speed...or...go well over in the high velocity offerings.
I've never shot a TOZ 99, but being a semi...it may end-up having some ammos it will cycle well...others that it won't. Don't buy too much of any one kind until you've tested it. I know my Marlin semis will eat almost any standard velocity ammo. Yours may too. Since you'll be looking at labels...avoid anything under 1,000 fps. (CCI Quiet @ about 710 fps) You won't bump into many that fall into this category. They won't have the juice to cycle the action on a semi.
For me, almost all of my guns shoot standard velocity ammo best. Federal Gold Medal target @ 1080fps. CCI Standard Velociey @ 1070 fps CCI Subsonic @ 1050 etc. They shoot well in my bolt guns and semis.
