I've got a chance to get a Polish Tantal for a really good price, I already know the stuff to look for before buying but my question is, is it really that great of a caliber? I've never fired a 5.45 so I know little about them other than waht I've read online. My other AK's are 7.62's, I love the idea of cheaper ammo and mags. So 5.45 owners are you glad you got yours?
