Hoover Meplat Trimmer Summary:
The Hoover Meplat Trimmer is the best tool on market for trimming
meplats. It features a proprietary radiused bullet stop that will
not damage the bullet and provides extreme repeatability. The Bullet
is held by its OD and is stopped on the ogive by the radiused bullet
stop for a square repeatable cut.
When uniforming bullets, you need the three major parts of the
bullet to be the same: The boat tail or base of the bullet, the
bearing surface length and the ogive.
When meplat trimming, you want to uniform the ogive length only. You
can’t use the base of the bullet to reference from or you will not
have uniform ogive lengths because of differences in bearing surface
length. Even if you sort your bearing surface lengths to within
.002” before trimming, a .002” difference in ogive length on a .308
6.8 caliber ogive with a meplat diameter of .070” will have a 5.5%
difference in the meplat’s frontal area. So it is a must to
reference off the ogive of the bullet for consistent meplat
Plastic body meplat trimmers that do reference off the ogive suffer
from body flex that allows the bullet to be “shoved” in by the
pressure being applied. This gives you inconsistent ogive lengths
and meplat diameters.
After trimming your meplats with the Hoover Meplat Trimmer, you can
sort your bullets by overall length because the ogive of the bullet
is consistent with the rest of the bullets. The only difference will
be in the bearing surface length. This process has been thoroughly
tested and works flawlessly.
Why should I meplat trim?
- Smaller group sizes
- More consistent velocities
- Lower extreme spread

How to check bearing surface length:
Slide calipers into
the slot on the Meplat Trimmer body. Close the calipers to square it
and tighten the black plastic thumb nut.
Install a bullet in
the Meplat body and close the calipers. Zero the calipers to get
your base number.
Sort bullets in
.001” increments (example -.002/-.001/.000/+.001/+.002) by
installing them into the Meplat body and closing the calipers.
