Most of my reloading career I have more or less went off recomended COAL. Im working up some loads with Berger 185 VLD's and having little luck in getting them to group very well out of my Sendero 300RUM. I have had the same luck with heavier VLD's and want to give them an honest effort as I have had GREAT luck with them in the past in other calibers. When Berger recomends holding them off the lands, how exactly do I measure this (.020 or whatever), this might be a dumb question but Im a little stumped??? Im what I consider a NEWBIE at this longrange reloading stuff so bear with me. Thanks ahead of time.
