Asking about the best 22LR ammo is a deep well. The only sure fact concerning accurate 22LR ammo and a specific rifle is that the ammo is consistently inconsistent. It also depends on the shooter's expectation of accuracy, how accurate the barrel can be, and the skill level of the shooter. I like how RWS's brochure grades their ammo and gives it an expectation of 10 shot groups at 1", 3/4", or 1/4" (converted to standard, of course). If asked, I think everyone would prefer to shoot 1/4", 5 shot groups at 50yds, but that's not always possible, even if you purchase the most expensive ammo. While nobody really wants to admit it, there is expensive ammo that shoots no better than inexpensive ammo in any specific rifle. The more expensive the ammo, the more statistically consistent it should be in terms of components and velocity. Consistent velocity, narrow ranges between lowest and highest velocity means a lower standard deviation and means fewer flyers, which should mean smaller groups. But it doesn't always work that way.
While I don't know what the OP's expectation is, if you've already used Wolf ME and liked it, 3/4"+ groups might be a disappointment to you. It is pretty well known that Lapua manufactures and rebrands SK and Wolf 22LR. Many people like SK standard+ target ammo. Ruag makes RWS, Norma, and Geco 22LR. And Eley of course. I would start at the bottom of their lines and work your way up until you either reach the accuracy limit or the end of your budget. As much as I dislike admitting it, the US-made 22LR doesn't hang with the European made 22LR. IMHO, I don't know why so many people like CCI SV (but it's never grouped that well for me). I wouldn't bother with minimags unless your expectation is 1.5" @50yds.
The other consideration is if you're trying to use the same ammo in the CZ452 and the 10/22. The most consistent ammo should be a RN or FP 40gr lead bullet at 1080fps. These may not run your 10/22, depending on how modified it is. You may need to run HV ammo in the 10/22. But then again, the expectation should be that the CZ452 should outshoot the 10/22.
