What do you want to do with it?
Stay away from hypersonic if you're wanting accuracy. It's good for the noise factor though.
Depending on your firearm, the hyper stuff will beat the crap out of it. Subsonic costs more, but it's more accurate and easier on the gun.
Do NOT waste your money on Remmington .22 ammo. Any of it.
.22s are in their own world when it comes to ammo. Serial# xxx123 may not like the same ammo as xxx124.
Good luck! You have a lotta research to do if you're looking for bug holes on paper. If'n yer just looking for plinking ammo, MiniMags and Federal bulk seem to rule the roost.
