good post. your friend(?) wants a lawn tractor but it must have a Chevrolet Performance ZZ427/480 HP motor installed to mow his 1/8th acre front yard! I get a kick out of these accurate 300 BO threads as there has been much debate regards the accuracy of that round. I think Wilson even went as far as to develop a new similar round for which they provide a slower twisted barrel. I mean how many match guns wear suppressors and feature 1-7 twisted barrels?
