In my 7mm WSM 139gr SST shoots great with bullet just in the lands. Not so with 162gr A-Max or 168gr Berger VLD ? Where you seating them in relation to rifling ?
Every rifle can be different but I've found the Amax like .010 of the lands to just touch. The bergers for me normaly like anywhere from just touch to .015 into the lands. Some people are getting good results with bergers of the lands but so far i havn't found this in the rifles I shoot.
