I've tried some factory bullets, (the 527 is a .310 bore, .308 is under size, sorry -
http://cz-usa.com/product/cz-527-carbine-7-62x39-5-rd-mag/ ), but I like the Hornady 123gr spire point for many uses. I have had pretty good luck with it over 27 grains of AA#1680 - my hunting load, if you will, being a soft point bullet. The selection of bullets for 7.62x39mm is pretty lean, compared to other 30 caliber bullets, but I found another way to broaden the spectrum - hand casting my own. This older picture also shows a Lyman bullet that I was gifted with several to try out - not bad at all.
This is my favorite, shown here hard lubed, as opposed to tumble lubed as in the above photo.
Thank you for the kind comments about my rifle stock - the maker and genius is in Mesa if you would like to contact him for rifle work.
PM for details, be happy to connect people looking for interesting stuff.
kawasakifreak - free brass? Nice score - that is the one thing that is the hardest to find for me. I have some brass with so many ejector dings in the rim that I cannot count how many times they've been loaded. Seriously.
