Forming 300 AAC from 223 cases

By LON H. on Feb 07, 2024
Used this die set to form 300 AAC brass from some reclaimed 224 brass and it worked great. I also loaded some sun Sonic 300 AAC rounds with it and was very pleased with the die set.

Great set

This is my first set from Lee, great overall and spectacular for the money. Great shipping as usual!

Lee 300 aac Blackout 3-Die Set

These dies work great for the 300 blackout, especially when converting .223/5.56 cases to 300 blackout. The crimping die is the best on the market in my opinion.

Liked this 3 die set so much...

By Steve D. on Dec 26, 2019
I've been using this Lee die set for several years now without troubles of any sort. Works well for reshaping .223/5.56 brass and the "factory crimp" die adjusts to yield the exact right amount of crimp for any bullet you may choose. Liked this die set so much I gave it as a Christmas present to a reloading buddy just now getting into 300 black-out!

300blk dies

By Jeff K. on Apr 16, 2019
Dies are OK. I use Lee for many pistol calibers. I had to mess with the decapper pin a bit, but once set it seems to be good. Will keep buying Lee dies.

I have used lots of different makers and always go back to Lee. cheaper, easier to set up, and work awesome in my Hornaday progressive press!
my first set was 9MM and made (at least) 20K rounds and still going!
