Anything built by Ruger is generally the strongest, toughest and most durable ever built. Bill Ruger truly was one of the all-time greatest contributors to the firearms/shooting world. The majority of the handguns and rifles I own are Rugers - because they always work and have never failed me. He built tough, reliable guns for the working man to take afield under the worst of conditions with confidence. Not always the prettiest or most "refined"
but by God you can bet they will stand up to anything.

I own five Ruger M77's... In 22 Rimfire, 44 Mag, 6.5 Swede (Mark II), 338 Win Mag (Mark II) and .458 Win Mag (Mark I). All are utterly reliable in every way.
