Thread: Finally a chance to work on the .300 Whisper brass...

Man that sure was aggrivating, but I got the dies set now! I looked on line and found some great info at Quarterbore's Forums.

Here's two dummy rounds I made.......lol I haven't figured out the COAL yet

wow! They look so wrong

when are you going to "powder" some up?

Thats just f'n wierd, but I bet it works well. Should feed pretty easy too due to the straight brass. How heavy are those bullets? What kinda velocity are you expecting?

The bullet looks bigger than the casing.

They ARE bigger!

Holy crap...

what is the parent cass and what are the load weights

Parent case is .223/5.56. Those are 220gr SMK's that will be sub-sonic for use in my AR15 and suppressor. I also have some 150 Noslers for hunting rounds.

I'm running 210, 220 and 240gr in mine at a 1:8 twist. I run 125gr Noslers for my Hunting rounds that duplicate 30-30 SSP rounds. Who's dies are you using? SSK? 300-221 fireball?
