Marking cases for consistent chamber alignment? How to?

[kraky2]

fyi--I tried indexing a few years ago in my hunting rifle. It didn't do anything for it. I also used to weight cases and bullets and found that didn't do anything either. All this might shrink a benchresters shooting at 1000 yds ever so slightly but is pretty much a waste of time in a factory hunting rifle. Time would probably be better spent practicing and looking for that "magic" load the gun just can't shoot badly!! Just my imho!
