Re: Heavier or lighter?
Light bullets have lower BC which means at LR, they slow down more and get bounced around by the wind. The heavies will also carry more momentum at the target which will help both expansion and penetration. You no longer have vel to do the work.
Go with the bullets already listed and you find that once you go past 500yds, there is no comparison to the lighter bullets.
I shoot a 30Gibbs with 165gr SST bullets at 2950fps. Up to 600yds, it performs quite well but gets blown around in any kind of wind beyond that.
Buddy shoots a 280 w/168gr MK. Lower muzzle vel but higher BC. He shoots through conditions that drive me nuts. Both rifles are 1/3MOA rifles.
