the diference in the length of the barrel is only going to amount to 50-100 fps diference in velocity ,wich can easily be compensated for with an adjustment to the actual load used.i have a m77 int. in 308 and a #1 int. in 30/06 love them both.the 308 is a short action very light and nice to tote around.your 30/06 will be a long action ,a little diference in length and overal weight but minimal.
the cz that was posted is also a very nice firearm except,if a ruger fits you comfortably you prob will not care for the cz.they are designed to be shot with open sights not a scope.notice on the posted pic how much of a drop there is from the top line of the barrel to the top of the stock.the ruger has about half that drop.i had a chance to buy a used one and passed it up for this reason.
the only common complaint about these rifles is of course rugers trigger,or sometimes a stock will change shape due to climatic conditons or poor storage practices affecting accuracy.
i have not worked up a real accurate load for my 308 i get like 2-2 1/2" groups at 100 yds,but my 30/06 will shoot sub 3/4" at the same distance.
i have several other rugers with full length wood,they don't make any much nicer.for the same money that is.good luck with your purchase.shawn
