I know that the 6.5x57 IS out there - aka the 25-06. But in my desire to jump into the high-end 22 cal game, I have decided to go beyond the 220, which I already have dies for. Now I want to go right to the most barrel-burning top-end 22CF case out there. I think that case might be the 22-06, which would be a necked-down 25-06 case, which is a necked-down 30-06 case. My questions are: Is that the one I should be looking for, or is there another one out there with even MORE oomph (powder capacity)? Since I don't really want to have to go custom on a die set, that round wouldn't still be under "wildcat" status, would it? If it is, then what IS the wildest (top) dog of the 22 cal variety, that is not so wild as to be cat? Also, if the above doen't pan out, what are the highest capacity [non-custom] .243/6mm case dies available?
