Yes, I am a loader and as far as long distance goes I think 300-350 is my max. The accuracy testament is only verbal, but he is trusted. Sounds like a 20 incher may not be a problem.

Another question----What about muzzle jump? One of the reasons I like the .204 is that you can see the "show" but with the shorter then average barrel do you think it will have considerably more jump to the point you cannot see your impact.

I just went to Rugers site and it seems as though they have discontinued the Mark II-----------bad idea in my mind!
