I am reloading Berger 168 vld's in a Remington 700 7mm. the load that is grouping the tightest is. 66.2 grains of H-1000. using a winchester case, CCI BR primer. The grouping is 5 shots in a 2x3 square at 100 yards. I know they can get much tighter. I am thinking of playing with the lands setting . as of right now all the cases are trimmed to 2. 490 and the Coal is 3.290. Thanks to the folks at Burger for giving me the reloading stuff. If I am wanting to jump into the lands should I shorten the Coal by .10 making the coal 3.280? or do you shorten the case?
