The reason I ask is because I've built a 6.8 SPC on a Savage action. I've got the groups down to 1" @100 yards. Not sure what to expect compared to my 22 and 6BR rounds. 90 grain Sierra HPFB will group pretty good. They set at the shoulder neck junction. The 90 grain Speer TNT FB is half way in the neck with the bullets jammed into the lands.(looks more like a Berger VLD) 110 grain Hornady V Max are much longer so I've got lots of working room. No "match" type bullets available that I've found. Any experience with the accuracy of a .270 (.277)?
