Ok im looking to build a 510 whisper rifle OR any 50 cal sub ammo rifle that can shoot the 50 cal bmg bullets mostly 750 Amax's.

What action is needed ? what is needed to make the ammo ?
What cases are used?
 
Re: Looking for info on .510 Whisper rilfe build or

my 510 is built on a phoenix long action but many other long actions will work. To answer your brass question you have to decide exactly what you will be building as there are several options that others have tried. I use cut/necked 338LM brass which is what the 510 Whisper was designed around. You will need a lathe to make the brass or have someone make it for you. The problem you might have is finding reloading dies as they can be hard to come by. CH4D offers dies but there can be a long wait at times

You could of course just jump in with both feet and buy the 510 package that is for sale right now in the FS section-

if you need any help with brass let me know and I can point you in the right direction
