I have a CZ 204 varmint walnut. With factory 32 gr it shoots 1/4 at 100 yds. The 40 gr factorys did about 1/2.
I haven't loaded anything for it yet so can't help you with any handloading info.

I think mine is great and don't think you can go wrong with one

I too have a 527 American in .204. Just posted my initial results the other day. Have only fired one box of Hornady 32gr loads. One ragged hole at 100yds on a few 3 shot groups, the worst were approx 1/4 inch. Next on my list is the same rifle a .17 Remington. Get one, you'll love it, too.
