Just wanting to know your opinions about Tilting Bolts Vs Rotating Bolts in Semi-Automatics? I like the Tilting Bolts from a simplicity and reliability standpoint and I feel that they are better "systems".....am I missing something?

I am not sure what you mean by "tilting bolt" unless you might be referring to a lever action rifle, and a "rotating bolt" generally refers to a bolt action rifle, and neither are semi-automatic. Most lower powered semi-automatic rifles use a recoil system to force the bolt backwards to discharge the spent round and load a new one, while higher powered use a gas system to operate a piston that rotates the bolt and moves the bolt backwards. I suggest reviewing the attached link for the Washington Hunters Education Program for basic details.
