300 blk or 556?

[The Sandman HD]

Friend of mine says to keep my AR in 556, I'm converting it to an sbr and using a Supressor and want to take it to 300 blk. Any thoughts on the 2 rounds in Supressor variant?

It's the easiest conversion. The only thing you have to change is the barrel. 300BLK uses the same bolt, mags, etc. And a .30 cal suppressor does very well for 5.56 also.

.300 suppresses much better.

How easy is 300 blk to find, and cost difference on the 2?

Its getting pretty easy to find. It's about the cost of .308 right now, you can find it less sometimes. It's a lot cheaper to reload if you have those capabilities.

I've never done any reloading, how much is it to get a full kit to do it?

depends on your preferences. That's like asking what kind of a car should you drive.

If you like to shoot a lot keep it .223.

I hand load and my 300 resides in the back of the safe since it costs twice as much to shoot as .223 for the same money spent. Sort of wish I would have kept it a .223.

If you want to hunt and or take advantage of full sound suppression 300 is it. Keep in mind it is more expensive and also a little harder to load for if trimming and forming your own brass.

That's the only thing that worries me about 300. With the sbr I'm building in trying to make it quiet as possible for fun, so I feel like 300 is the only way to go.

.300 is definitely the quiet caliber. If you want quiet, .300 is the [STRIKE]droids[/STRIKE] round you were looking for

Haha I agree, don't think there is any reason to not go with it.

Worth it to keep an extra upper for the 556 around though?
