I find that I don't have to treat HAM'R brass like 300B brass. Meaning that I don't use my HF cutter. I first take clean and lubbed (outside and inside the neck) 223 brass and immediately resize it in the 300H die. I go slow on the first resize, then give the case a ⅓ turn and resize it again. Using LC brass, I've so far only had one neck split. Then I trim in a Little Crow 300B trimmer that was reset with a fully processed 300H brass. It works perfectly. Zero issues. My brass trims at 1.595 (+/- .002). Very consistent. Once it's trimmed, I then chamfer, debur, clean the flash hole, primer pocket, and then drop it in a 300 HAM'R case guage. It's beautiful!
No he is creating .300HAM'R. As he said, his measurement of case length is 1.603 when the length of the .300BO case is 1.368. It's easy to cross up the names when have so many rolling around in the mind.
@@RideForLifeCR250R He might have changed 223/556 to blackout then to HAM'r if you pay attention to his wording and where/when he says blackout because maybe somewhere in the process of getting the 300HAMR it is cut or shaped like the 300BLACKOUT
All I need to make excellent 300 HAM'R brass is the Lee 300 HAM'R die set and a Little Crow 300 BLACKOUT trimmer. I set the trimmer to 1.595" and it works perfectly. I then finish processing the brass as you would any rifle brass. I don't use my HF cutting wheel at all in the process.
So, in other words your making .300AAC Blackout cases??? Looking at the SAAMI specs, there's quite a difference where the shoulder is, but you don't tell us where to set the sizing die to get the proper height of the shoulder...

I'm thinking he meant ⚒ since thats the title of the vid
Thank you!
300 hammer or blackout?
That's exactly 💯💪. Thanks Again
Good stuff big dog, I appreciate your know how
So your using a 300blk sizing die to form the shoulder. ???
Did you size it in the LEE to 300BLK??? That's what you said anyhow.

LEE makes 300 HAMR dies. He is using the 300 AAC Dillon Trimmer.
LMAO
Well all i have to say is that was as confusing as anyone could make it .
