[QUOTE="robbobsam, post: 471228, member: 25432"] 95grain VLD'S are a long bullet for a .243 and I suspect your barrel is a 1 in 10 so it will not stabilize the VLD. I know because I have tried and tried and tried again. If you want a 100grain bullet use the Speer grandslam, it is a lot shorter. Stability is not about weight, it is more to do with length of bullet. Check out what I am saying here. >>>>[url=http://www.jbmballistics.com/cgi-bin/jbmstab-5.1.cgi]JBM - Calculations - Stability[/url] You can check the length of your bullets here >>> [url=http://www.jbmballistics.com/ballistics/lengths/lengths.shtml]JBM - Bullet Length List[/url] The berger VLD is 1.15" long. I just did the calcs and in order to get stability with this software you need a reading of 1.3-2.0 With a length of 1.15 and a velocity of 3000fps and a twist of 1 in 10 it gives a reading of 1.084, which means UNSTABLE IN FLIGHT !!! You need a minimum of 1 in 9 twist for Berger VLD's in .243 !!! [/QUOTE]
