REdding make the dies, they're called .300-221

[mark223556]

No, you need to reduce the legth of the case to the same as a .221 Fireball and then neck it to .30.

You can use .221 Fireball brass and neck up but we have .223 brass in abundance so use that

@mark223556 , Can you help a fellow shooter out, Who makes .300 Whisper dies? Or do I need a custom set?

would you please post what you are doing here, step by step. I see that you are using a dillon progressive loader, what other tools are you using in this(hint hint) am I hearing a shop vac, or is that another power tool?

One other thing, the .308 trim die must be shortened .600"

[xangar]

It looks like the case is coming out of the trimmer with the neck sized to .30. Does the sizing happen at the same time its in the trimmer? Is it going into any dies after that? Nice setup, I'm trying to get one together right now for my .300blk

@slimjim561 With a small case capacity, fast powders, and heavy bullets, it's capable of getting a 240 grain bullet to the speed of sound and having little pressure left at the muzzle. Plus, since there's less case capacity, loads will be more consistant and safer than regular gallery loads from a .308 or .30-06 case. And since the case and the whole cartridge itself is so short, it can fit in an AR-15, which the brief pulse of gas can still cycle with the right gas system.

whats so special about this round?

@mark223556 Thanks mate I'll order a set.

That's not really a good option for anyone who travels, different state statues would consider a NFA device contraband so having the ability to store your (CAN/SBR/SBS) and take your weapon with you from state to state would be a good option to keep.

[rollmasterross]

Don't forget the stamp for the silencer/can too.

You could save the cost of one stamp by getting the can permanently mounted to the barrel so that the effective barrel length is >=16" . You'd have to blind pin or silver solder the silencer to the muzzle. Not sure that most people would want to have a ~$600 rifle can permanently attached though.
