IMHO, it is not only is more affordable, but shows up any shooting flaws with more visibility, especially shooting . so since i've been tinkering with the .22 heavily over the last 2 years, i thought i'd send some .308 down range to see if there was improvement. beginning of last year, was averaging 5shot groups with the .308 at 100 = -1". this year .6" beginning of last year, was averaging 5shot groups with the .308 at 200 = -2". this year 1.5" the same goes for all distances up to 550 yards where i start going above MOA. improving my 5shot centerfire groups by .25 to .75 inch or more. seems all that affordable shooting with the .22lr paid off better than i thought, and by approaching the .22lr in a serious manner (rifle, ammo, and technique) has paid off in the centerfire arena. i know it's been talked about before, just wanted to throw in 2 more cents, and will probably be doing more rimfire stuff in 2010 than ever before. alot of folks ask me why i'm "playing" with the .22, that i should stop playing with "toys" and go back to the "real thing". looks like playtime paid off!
