Thread: Micrometer Dies

Redding, Wilson and Forster are my preference for micrometer dies. All mine are Redding and Forster. Would love to try Wilson but need an arbor press.
To use these dies well you really need something to give a reference. i.e. a micrometer and ogive gauge (Hornady LNL bullet comparator etc) or your flying blind. Some bullets are more consistent than others. For example the 85 HPBT I run in the 243 are often 0.020" in variation. If your using a 0.010" jump then you could be anything from just right to 0.010" jam. Quite a difference.
The micrometer is nice to return to for seating different bullets as they return to same point every time. Typically they're are a better seater with floating sleeve that make for better concentricity.

Are you seating long and then dialling the micrometer the last 25 thou for every projectile ?

If for example the projectiles differ by up to 5 thou then seat 10 thou long and dial the remainder after measuring the seated projectile

It gets tedious for every one but its worth it.

Which is the whole point.
