I agree with mmb713.

I find Varget a bit too slow for a 24 inch barrel .223 CZ 527 that has a 1:9 twist.

H335 is a top performer along with H4895.
H322 is also a good powder but hasn't been able to match the accuracy of either H335 or H4895.

Of my top 25 loads with my CZ, 7 are with H335 and 18 are with H4895. As of last weekend, the top 25 loads average 0.437 with a total of 246 measured groups at 100 yards with bullet weights ranging from 45 to 63 grains.

But of the top 5 that average 0.395 with 104 groups and 3 loads including the two most accurate are with H335. Bullet weights include 45, 52 and 55 grain bullets.

Your results will depend upon your stock/barrel combination but I think that powders in the speed range of H335 are more suited to the .223 at weights under 69 grains.
