I shot a good bit of the 7.62X39 out of a rather nice Russian SKS. They were dirty, not super accurate and tended to foul things. I tried the Wolf Gold (brass) in my .22-250 with pretty much the same result. Oh, almost forgot, shot a couple of boxes in my .30-06 with miserable results, the Gold that is. I guess for plinking they'd be fine, but I wouldn't hunt with them.
My philosopy is if you're going to buy a licence, buy the hunting gear, take time off work to hunt, scour the woods for days for a single shot, why not get the best bullet money can buy for your rifle. What could it be, an extra 25 or thirty bucks? Why risk the whole experience with an inferior bullet.
