300 Blackout "Blanks"

[skeetman77]

Anyone ever make blanks for their 300 blackout? I recently bought a golf ball launcher and wanted to use it on my 300 blk.
Thanks

I am somewhere between

-DONT DO IT

and

-DO IT, THIS COULD BE AWESOME


Beyond that I have nothing to offer of substance!

Do you need a blank like a 5.56 blank that will actually produce gas and cycle the action?

Or do you just need the primer shot?

Im thinking its the former and I have no clue how to tell you to proceed except very carefully.

I personally think I would use 5.56 blanks on a 5.56 upper as they are relatively easy to get a hold of.

I will neither confirm or deny a "friend" taking a regular loaded 5.56 blank and putting it thru a 300blk sizer. Then firing said blank in a 300blk 16 inch gun with a blank adapter.

This is 100% for the fun of launching golf balls 300-400 yards. I found a company www.atlanticwallblanks.com that can make them for me but I haven't seen the price yet.

I thought about taking the M2000 (5.56 blank) and running them through the 300 sizer.
BUT the thought of my machine exploding in my face has deterred me from that approach.

Thanks guys!

How about making your own?

Star crimp dies, 30 cal. is available.

I will look into the crimp die route. Which powder would you recommend? How much?
Thanks Dellet....

For what you're trying to do, I honestly have know idea. The goal for making blanks for me was noise.

Since you are trying to launch something, I have know idea how that would work. Not sure what the added pressure of the golf ball might do.

It's been a long time but 10 grains of Unique for a 30-30 blank comes to mind.

For shotgun I just replaced the shot with a filler like cornmeal and used about 75% load on the powder i normally used. These were used training dogs.

The idea with pistol or rifle blanks is to make noise and then drop pressure as quickly as possible for safety reasons. So in general a very fast powder. Actual commercial blanks used a purpose blend powder that I could never find a source for but that was pre-internet days.

I would probably search "Bob Shell" and variations of blanks and custom cartridges. He has written extensively about creating obsolete cartridges for shooting antiques both live fire and exhibition. here's a start

I have, i mean my "friend" has sized a 100 plus. and fired them. as long as you use enough lube, it is not a problem. However i did, I mean he did need to use a .222 die set to squeeze the tips down enough to fit inside the chamber. without doing so, the last little bit would not allow it to chamber.

I use the .22 blanks at Home Depot to launch golf balls. They are sold in different power levels. I use a pistol and with the strongest it will launch them over 100 yards.

You can also use them to launch .22 pellets out of a real gun.

I will let you know how it works out.
