[QUOTE="pills, post: 865822, member: 22576"] No . I measured the OAl to the lands to be 3.044 with the 140 accubond. Tried from there shorter without getting good results. I even called Cooper who told me they got their best loads with RE22 and a 142 SMK seated to an OAL of 3.000. I know its a different bullet but if figured I would give this OAL a shot with the accubond. Still no good. I got ahold of some 140 bergers and I made the 1st loads with the dies set the same as I had for the accubonds. I knew due to the profile this would be longer but should be the same distance off the lands. They shot great at this length so I didn't mess with it anymore. I think the OAL is 3.100. I see that berger manual and also nosler list the OAL to be 3.228 if I remember right. I could not come anywhere close to this with the accubond. Cooper told me they have "tight" chambers and that I should not necksize only. also told me not to use Blackhills ammo in the 6.5x284 because it would be too hot. [/QUOTE]
