You can probably fine CCi standard and green at most gun shops to try After that ordeing good stanadard velocity 22 ammo never seemed hard. Wolf and the same ammo SK have the same 2 loads made by lapua. federal has a low cost 711B and the better yet affordable line there 922A and there ulra match in the 15 dollar range and these two are loaded by loaded by RWS. Eley is the other label. Order here for most labels -
If you get serious about match shooting they will let you pick out of different lot numbers and when you find your favorate you can buy in bulk from one lot. Not that way when ordering from most catolag stores.
mountainman 13 I seem to find that standard velocity .22lr shoots fine from a pair of ruger mkIII, a colt huntsman a pair of ruger 10/22 and son in laws marlin 795. Thats all we shoot.
