Do you have a RCBS bullet puller collet that you can check the thread size & measure the length and diameter?

I have an old RCBS case trimmer and am wondering if the bullet puller collets are the same size and use the same threads (3/8-16) as the case trimmer collets? If they do I am thinking I can use a bullet puller collet, in the trimmer body, to hollowpoint some cast "boolits". Apparently "boolits" is the accepted spelling in the cast bullet community.

My favorite Mark Twain quote. "I don’t trust a man that can only spell a word one way."

Thanks Ken

This just might work. A trimmer collet is .556 dia and is 1.870 long.

I have a .330 AAC Blackout upper, and a Lee TL309-230-5R 30 Caliber mold on the way. I am thinking about powder coating the bullets, that is the reason for the hollow point so I can stand them on pins to do the coating and baking. My idea is to chuck the bullets in the collet and use a center drill in place of the cutter.
