Ruger Mini 14 Ranch rifle?

I own a Mini 14 and love it.As for the mags I've found the Pro Mag 20 rounders seem to do good but have only found 3 - 30 rounders that worked good and they where the composite ones.As for Ammo I've shot thousands of rounds of Wolf (very dirty ammo)Remington and Winchester the only trouble was 1 stovepipe and hangups with the 30 round Mags, no hangs with 20 round mags.Also from everything I've read and according to an email I sent Ruger the Mini14 will shoot the 556 NATO round.Also another thing I do with a gun is to see how dirty I can get it before I start to have trouble with it working right.Other than the 1 stovepipe it just kept shooting.After about 3000 rounds I just broke down and cleaned it(what a mess)but it just kept shooting.Also the $800 price isn't to bad.
