? about reaming .223 crimped primers

[Wannashootit]

I have a batch of .223 LC brass that I want to reload.
I have punched out the primers with a Lee decapping die, and will be using a Lyman reamer...

After depriming, I checked fit with the reamer. The smaller dia. bottom section slid right in. I'm trying to discern how much I'm trying to remove. The "crimped" area is very small. In fact, I've had a couple of them "slip" into my Winchester brass and they decapped and primed without a problem in my Hornady progressive without me even knowing it at the time.

I have it chucked into a variable speed drill (I'm assuming a slow speed is preferred). Is the reamer calibrated to remove the correct amount of material when it "bottoms out" at the bottom of the primer pocket? Just want to make sure I don't end up removing too much material, and ruin or end up with unsafe brass...

Thanks...

The Lyman reamer has a angle cut into the leading edge of the reamer. This does 2 things.

1. Makes it easier to get into the hole.
2. Make a positive non cutting stop when it hits bottom.

I've used one for years on LC brass mounted in a drill press (quieter than a hand drill).

Cheers,

Doc
