Once your over 24 in. the extra velosity gain per extra in. of barrel goes down fast. If your wanting every little bit you can get use it all, but be aware that your gun gets heaver also. I have a 26 in. heavy barreled .22-250 with a maple stock that weights 14 1/2 lbs. , great from the bench but gets heavy just getting it there. /ubbthreads/images/graemlins/blush.gif Consider the weight of your gun and purpose also.
