So I will own up to a moment that I second guessed Ruger on ammo selection. I bought a Mini-14 and like a good boy I read the owner's manual before I took it to the range. Well, somewhere in the manual it states that they suggest against using any ammunition that is not manufactured within the USA. I cant remember if I called them and asked them about it, or if it later gave an example of using Wolf Ammo... either way, they advised explicitly against Wolf due to extra hard primers that can cause the firing pin to break.
Me, being an arrogant young punk, I decided to shoot some Wolf out of it anyways because I didnt want to spend the extra money on American ammo ( I think a box of 20 rounds of Wolf cost only about $6.00 at the time, and cheaper American Eagle was about $10.00 per 20). And I shot 200 or so rounds out of the rifle without a problem, and one day I pulled the trigger and heard the firing pin come down, but no bang. Thinking it was a misfire I chambered another round and then another and another... soon enough I realized that there was no dimple on these primers. Then I realized that I broke my firing pin!
Unfortunately for me, the Mini-14's firing pin wasnt an easy replacement like on an AR-15, so I had to send it back to Ruger for repair (at my expense). And I got a nice little note with my rifle once it was repaired that simply said something to the effect of "Please do not shoot Wolf Ammunition out of this rifle again."
It doesnt seem like the rifle repair was horribly expensive, but it did take about a month to get it back and that was inconvenient for me.
Moral of the story- the manufacturers know what their guns should and shouldnt shoot. Dont second guess them.
