[QUOTE="westcliffe01, post: 912089, member: 35183"] You need to do a proper ladder test to determine the powder charge that results in the least vertical dispersion. It has to do with the harmonic vibration of your barrel and will be very specific to your rifle and your barrel. Its not an intuitive subject, but you can see an analysis done on a barrel here [url=http://varmintal.com/amode.htm]Barrel Harmonics Mode Shape Movies[/url] that I think will illustrate the point. Most of the time shooting a max load or close to it is a good way to get some pretty big groups and wear the throat out really quick. [/QUOTE]
