There is lots of talk about steel cased ammo like Wolf causing damage to your rifle with that super hard steel case when compared to brass. I personally think there maybe something else at hand. I read a great article in USPSA's May/June 2011 publication of "Front Sight" magazine. The article titled "Steel Core Ammo: Fact and Fiction" was written by Eric Jay Miller and is the basis for my video below.
