HotGuns: Where can you get .300 Whisper ammo and how much does it cost by box and case?

Ive never bought any so I cant say.
I make my own.

I cut .223 cases off at the neck then run them through a Redding sizing die. Then I trim them to the same length.Thats all it takes.

I modified a key cutting machine and put a slitting disk on it and made a vise to hold the cases. It takes about 4 secons to cut one off and its repeatable to a couple of thousanths of an inch.

I usually use 220 grain Sierra Match bullets. It takesa 1 in 8 twist barrel to properly stabilize them. Most .30 barrels are a 1 in 10 and only work up to about 180 when things go subsonic. The Model 1 Sales barrels are 1 in 8 for that very reason.

Damn...too much work for me. ANYBODY out there have a source on ammo in .300 Whisper? Or maybe a link to JDJ? Do they sell the ammo?

BTW, what does a normal pressure load sound like in .300 Whisper? How about a subsonic load (UNsuppressed)?

A round moving around 2200 FPS sounds about like a 30-30 going off.
An unsuppressed round that is subsonic sounds not to much different but certainly not enough to hurt your ears.

What suprises people about the suppressed rounds are the strike of the bullet hitting the target. Most people have never heard a bullet strike.
If you take a brick and thow it against a 4x8 sheet of plywood that is leaning up against a tree...thats about what a 220 grainer sounds like when it hits a hard target. Muzzle noise is about like a pellet rifle.

I know of one source that sells cases. Ill look it up and find the link.
