I've noticed that when switching from one ammo type to another, that it takes a couple dozen rounds through the barrel before the ammo is shooting its best groups. The barrel needs to clear out the lube from the previous ammo and "seasoned" with the new ammo's lube. I think the SK+ will likely shoot tighter groups if you run more rounds through the barrel consecutively. I wouldn't be surprised if the groups end up being 1/2 to 1/3 the size of the MiniMags.

I have found that subsonic ammo works best for me. My CZ 455 likes SK Std + better than RWS R-50, although this batch proved to be very good. These targets were at 50 yds. The first four were 5 shot groups, the rest were single shots.

Someone posted question if a rimfire rifle can actually shoot 1 MOA and sure some will out to 100 yards. Helps if no wind/in-door and bench rest with high magnification scope combined with a good barrel, good ammo and good trigger. True if all the stars are aligned properly especially for 100ydsNo surprise that the SK out shot the other ammos, subsonic will always outperform HVTrue, verified by a visit to the factory by a trusted member on Rimfirecentral.


Nice shooting given that you were using a 4X scope. Groups would tighten up with an 18 or 24X scope.

Yup, concur that the major distinction you're seeing may be due to the transonic transition. You might try again at 25 yards and see if you still get those differences. Mini-mag will still be supersonic at 50, but possibly not the others, except of course for the SK which is subsonic as you know.

My CZ 452 shoots SK (and Rem Subsonic!) about the same, sub-MOA as far as I've put up paper. But it's less sensitive to poor ammo, printing about 1 MOA with Blazer (for instance) out to about 50 yards. Beyond that, however, Blazer goes to heck. Not entirely the rifle's fault.

Good test, though. Just not quite finished!
