300 AAC Blackout Bullet Seater

Bullet seater die for 300 blackout.

Insert is for a NOE 311-199 but should work well with many spire point bullets - If you need a different nose design, drop a comment with a link to the mold. A good resolution image of the bullet with a scale (ruler) can be used but isn't ideal.

Flip the Jam nut over before printing (less distortion on the threads) for easier threading. If printed as is, a little cleanup of the first thread might be needed and the nut will act like a lock nut.

Added seater stems for:
Lee TL309-230-5R
Hornady 30 Cal .308 155 gr BTHP Match (#3039)

If any of my designs help you out, a comment is appreciated and tips are always welcome.
