I have a CZ bolt action 7.62 X 39 and it is very accurate with almost every type of ammo. I've tried. Those Barnes bullets are great and it's good to know that they are meant for this caliber. I need to find some since I plan on doing some short range deer and hog hunting here on my property. I have RE 7 but not H4198. Do have IMR 4198 though. I bought a pound of CFE BLK recently and it looks like it would be great in the Russian round. Anyone use it? Share some experience and data if you have some please.
