[QUOTE="A A Ron, post: 2933985, member: 117277"] Curious how close the relationship between the free bore and barrel harmics is? For example in my rifle a 190 ABLR shoots best at .140" jump. That jump causes the bullet to be seated deeply in the case using up capacity and it is way past the neck shoulder junction. So if the throat was cut .140" deeper or so could you move the bullet the same jump to get back to node? My guess is the changing pressure, changing velocity, and changing harmonics timing would necessitate a complete new work up. [/QUOTE]
