Reeder Custom Guns - 25-20 Bullets - Bring on the O.C.D. jokes...

I pushed cast bullets thru the chamber throats and compared them to bullets sized thru the Lee Sizer.

The die was sizing them .0006" smaller than the gun.

So I chucked a bore mop in a drill and broke out the Corbin Bore Lap Compound. It took a bit, but now bullets are sized .0002" under throat size.

It gets difficult to measure that close. Had to break out my best micrometer. A caliper just wasn't cutting it.

Bullets definitely come out sized with a smooth finish now. I may try it out and remove another .0001", but doubt that's needed.

This has been a fun and worthwhile project.

put the letters in the right order...... CDO. Now that’s a bit much.

I almost pulled my hair out trying to accurately measure chamber throats. Pin gauges rule.

On it so you can apply the exact same pressure every time you measure. Its not really necessary, but fun to tinker with.

Gor some pin gages to vheck the throats and cylinders on my revolvers!

Have been 100% satisfied. They are all right on by my Starrett Micrometer. Be sure to get the .002" Minus Set.
