I`ve had better luck with BLc-2 powder than any other in the .223 in most guns. I load only ball powders because I load on a 550 Dillon, but you should get good accuracy with any powder near the burn rate of the BLc-2. H-322 and H-335 work real well also.

DIVR6347,  the 52 grain matchking shoots better than anything I have found so far in my 527. I load 27 grains of Varget and groups avarage 1/2 inch or sometime a little less at a 100 yards. This being said my friend had a 527 just like mine and it would not shoot my loads or much of anything else very well. He traded it for a rem. 700 22-250. You will just have to try different loads to find what your rifle likes.I tried several different powders,primers and bullets before I found one it liked. The cz's I have shot seem to be a bit more pickie in what they like than other rifles I have loaded for. Hope this helps and good luck.

I shoot the Sierra 52gr. HPBT Matchking in several different calibers.  With my .222Rem IMR4198 seems to perform the best.  It is also the best performer in my .222Rem.Mag.  By the time we get up to the .22-250 IMR4064 becomes the most accurate powder.  Your .223 has about the same powder capacity as my .222Rem. Mag. so I would think IMR4198 would be the ideal powder for it also.  This is oly for IMR powders though.
Best wishes.
