17-5.56 Seating

[simo]

So, I found it impossible for me to keep the little flat base bullet balanced on the case for seating. So I got creative. I took a spent .17HMR case and cut it with a small tubing cutter, took my time so it didn't crimp the cut end too much. I place that on my case, then slide the new bullet in, and it holds it quite well. I just tap it to get the bullet seated, maybe 1/16" in, then bring the press down and pull the .17HMR sleeve off, then finish the seating. Works great. Finngineered.

Try a seating die that has a collar that slides down and secures the bullet (Hornady style). Makes seating tiny bullets way easier.

Chamfer and deburring the case mouth helps.

RCBS gold medal dies are the ticket in my book. I have 17/20/22, 6mm.
They can be adjusted to work on long short and in between. Just need to swap shell holders, fyi they are the extended ones.
Makes life easy.

I've never had problems with 17-223, 17 mach IV, or 17 hornet. But I have don't have sausage fingers.
