Lee Precision Carbide Undersized Sizer Die 45 ACP

Good to prevent bullet push back. This can raise pressures to unwanted levels if loading full powder loads

I like Lee for my turret press. I have a hard time matching other dies because the lock rings sometimes interfere on the turret. The Lee ones obviously work with other Lee products. This undersized model is smooth, handy, and is also good for my hand press where I spend time decapping and re-sizing.

Before buying this die the neck tension on my reloads was all over the map and I was getting bullet set back, especially on thin walled brass or brass reloaded many times that has thinned out.
This die is the cure.
You can feel the difference when seating, nice consistent pressure.
I have no more set back and accuracy has improved since the pressure levels are consistent.
