So David, let me get this straight... A barrel with a more slender contour that heats up is not going to produce more deviation in its groups and wander than a the same exact rifle thicker barrel. I always thought it was the other way around that the heavier a contour of a barrel and the more time allowed between shots would make the deviation less and the groups better.
I didn't say a slender barrel won't produce more deviation in its groups. It shouldn't start throwing shots just because its hot.
