[QUOTE="sliceman, post: 654983, member: 24539"] I am planning my first long range build in 7mmRM on a trued early 80's 700 action. I am looking at 9-10 lbs or so final weight with a 26" Broughton or Krieger 1 in 9 twist barrel, utilizing 168 or 180 Berger VLD's or 162 AMAX. I have a couple of questions that I hope someone more experinced in doing these builds can answer: Which chamber neck size: .311 requiring neck turning .315 could use factory ammo if clearance OK .318 which I believe is the SAAMI standard Which barrel contour? I am thinking #5 or #6, preferring #6 (.750 muzzle diameter) although this might make it too heavy. Once built, I will work with it at ranges up to 800 yds but would go to a 1000 on deer sized game if the accuracy is there (and the shooter is capable!) Your thoughts would be appreciated. Thanks, HS [/QUOTE]
