Well you were right on about that Savage. I finally got some range time today, and ran about 600 rounds of a dozen different types of ammo thru it. Quickly, as I was paying by the hour, it got hot. I had some failure to feed with wincester ranger ammo, but it ate every thing else no problem. Even when hot and I did not clean it during my session. Shoot the devil out of it I did. I shot $10 a box ammo and I shot $30 a box ammo and everything in between. Now that being said it did show a preference for Federal American Eagle 147 grain FMJ Flat Point ammo. Is this strictly target ammo or is it also useful for self defense?
