For what it's worth, my Mini 30 does not like Wolf ammo at all. Golden Tiger is even worse. Of all the inexpensive brands that I've tried, Fiocchi has worked best for me. It's a little more expensive than Wolf & the other Russian brands, but still about half the price of the American brands. From what I understand, it's now being made in the US. Sellier & Bellot is another inexpensive brand that is supposed to be pretty good, although I haven't had a chance to try it yet.
