Throat length, does it really matter that much?

[QUOTE="dkhunt14, post: 1003776, member: 14053"] This is not what I have seen over the Chronograph. I shoot all my VLD's 10 to 15 in no matter if it is a 6 Dasher or a 300 WSM. I got increases in velocity and less pressure with throating the guns out and keeping the bullet in. This was done with at least 3 Dashers and a bunch of WSM and most of the time it was close to 100 feet gain. How can a program predict when it doesn't know how tight the barrel is? I have seen a hundred or more feet difference in the same brand. Seen more by going to a different brand. How does it know if my Bergers are .3079 or .3086 Diam. That changes velocity and pressure also. I believe they can be helpful but are not absolute. My chronograph and drops for 1000 yards verify this. Matt [/QUOTE]
