I'll keep this short, as I have a tendency to get long-winded on reviews. I bought this rifle thinking I was going to cycle lots and lots of imported, steel cased ammo through it. Wrong. I, like many others, have made this mistake. The Mini series runs on a tried and true platform. It's been around for a BUNCH of years for a reason. They are GREAT rifles. But they, by design, don't reliably run steel ammo, right out of the box. These rifles were made to run American brass ammo. By design, they are made to strike softer primers. By design, they strike "lighter" and do not, from the factory, impart hard enough strikes to RELIABLY ignite steel cased ammo. I'm sure some are already shaking their heads and calling me names. If you've done your research, and know your ammo, you are in the group nodding their heads saying "yup, this is right". Import, steel cased ammo has different metallurgy used in the primers specifically. There are reasons for this, which I won't go into here since this is a GUN REVIEW. If your intent is to buy a Mini 30, pull it out of the box, and run through piles of steel or surplus ammo, let me save you some frustration and say "DON'T buy this rifle". It will, out of the box, run all day long on brass, American ammo. And it will run steel, unreliably. You will have some steel ammo that runs better and more reliably than others, but it will NEVER, out of the box, run as reliably as it will with brass. Yes, you can change to higher spring rates and firing pin configurations to more reliably use steel ammo. This is why I keep mentioning "out of the box". Summary: (didn't he say he was going to keep this short) The Ruger Mini series are fantastic, ultra-rugged, reliable, tried and true rifles. Just keep the above information in mind while making your purchase decision and you won't be disappointed in the end. If you think I'm bluffing or full of fertilizer, ask around to those who know about Mini's. Heck, ask Ruger. They have FANTASTIC customer service response.
