Bullet Seating Tools allow you to precisely adjust and set bullet seating depth in very fine increments. Bullet Trimming tools or Meplat tools, trim bullet tips to achieve Uniform tips. This reduces the ballistic coefficient marginally, but the increase in consistency greatly makes up for the loss in BC.
Bullet sorting tools measure from the base to the ogive. Serious long range marksmen sort bullets according to this length and load batches to ensure the same ‘jump’ to the rifling with each cartridge. 4 – 5 thou is considered the maximum difference in length for each batch of bullets.
If you are serious about accuracy, you should consider using these tools.
