Well, here's my two cents. I was hesitant to try Russian primers too, right up to the point where I actually got some. These Wolf (and when you can get them, Magtech) are stellar performers. They are very consistent, and I perceive no difference between them and CCi BRs in my Varmint 22 250. I've never had a misfire in my 45 ACP, they are boxed so that you don't have to flip them to load them in the primer pickup tubes. They are clean burning, and even under a microscope (yea, pretty picky, huh), they are beautifully manufactured.
So, except for my DA revolver that is set for Federal, everything else, including my 22 250 and 223 Super 14, get Wolf.
I love them, but Powder Valley Inc has them cheaper than Wideners ($3.50 per box less). When these times of trouble are over, I'm going to remember who kept my costs down.
