I just saw an article by John Barsness in the latest Hodgdon Reloading Manual on accuracy tips for copper and copper-alloy bullets. Basically, the biggest tip was to seat them deeper for a longer jump to the lands--about .050" to .100" For me, shooting the older Barnes was always hit or miss with accuracy. I wouldn't mind taking another dive into the pool, however. So any suggestions on specific components or reloading techniques to improve accuracy would be appreciated. I'd be shooting 6.5 PRC, .280 Rem. and 7mm Rem Mag.
