I have had all the parts for my 510 whisper build for a while but just have not gotten out there and plumbed it up. I think one of the things holding me back is my lack of desire to make the brass. Anybody know anyone selling .510 Whisper Brass?

I would ask over at the quarterbore forums website. I think some folks over there may have them.

Yea, I figured one of those guys posted here and would answer. I cannot recall my username and password at quarterbore.

I've always thought one would be pretty cool to have.
What action are you using for the build?
I need details man... details!

It is a lawton 7500 repeater with a 338 lapua boltface. Bobby Lawton did me a .50 cal fast twist barrel. I am using some Seekins DBM and a MCM A-5 and will be using a jewell trigger. I got my dies from CH4D. I plan to build a Form 1 supressor if I ever get off my butt and send the forms to ATF. I have had all the parts for a while but I have not been inclined to make the brass. I guess I will have to drag out my reamer print and figure out the best way to turn the shoulder on some cases.

Sounds like an awesome build.
Having to turn a shoulder on the case has always been the one bug in the ointment for me.
I keep thinking about putting together a .375 or .416 Whisper to monkey around with.
