Just ventured into the .300 BLK world.
Cut my first batch of .223 cases down.
Started prepping them based on my hornady handbook (9th edition).
it states, (on page 380 if you're looking), that the max. case length is 1.40" and a trim length of 1.39"
which is how I prepped them.
After some double checking of other sources, I don't see anyone (including SAAMI) that reccommends a case length that exceeds 1.368" with a minimum length of 1.348" for the blackout case.
Hornady's data states it's numbers are for blackout and whisper.
Are the Hornady numbers wrong? Or based on the non standardized whisper case?
If so, why don't they differentiate between the two loads?
So, in short, looking for some INGO insight and wisdom as to what is working for them on .300 BLK
**if it matters, my loads will all be supers with 125 or 150 FMJ's using 'LIL Gun.
