Re: 300 grain, .338 SMK, BULLET POINTING - TIPPING?
Tipping, ie putting plastic tips in can only be done in labor intensive manner. Dave Tooley has probably worked this more than anyone.
Metplat trimming to uniform the OAL and then repointing using the Whidden tool has proven to give more uniform groups and eliminate some vertical in comp level.
As stated previously, trimming will decrease BC slightly and repointing will give slight increase.
