Ripp, that is a good article and gives us new ideas, like the effect of barrel contour, to think about.
However I am with Daryl on the accuracy stakes. With the exception of my 35Whelen which has a Walter Lothar barrel all my best shooters have hammer forged barrels. Also Blaser (and whoever the parent company is) use hammer forged barrels. Not heard of a Blaser that does not shot small groups. Same for Sako and Tikka barrels.
