300 blackout
 

So, what's the deal with this new cartridge? Why or is it any better than a 300 whisper 300/221 fireball?? Is it still made from .223 brass?

thanks,

About the same but was submitted to SAAMI as a standard. The velocity is a bit higher due to longer freebore - like 5.56mm compared to 223.

basically the same critter. although JDJ will prolly disagree!:grin:

I imagine if JDJ had ben a little more flexible, instead of demanding royalties, could have submitted the whisper for SAAMI and there would not have been a need for the 300blk or all of the other 300whatever names

300 whisper
 

My gunsmith called him to get a reamer. No WAy Hosea,,, $700 for him to chamber5 and install a standard douglas bbl on my action.
Nope/ went 300/221 bought a reamer and the gauges,,, He could have rented one out and made 50 bucks from most everyone on here.

Pacific Tool and Gauge has them. . .

You're EXACTLY RIGHT! Now look at all the publicity his round WONT get all because of pride and arrogance.(IMO) Its a shame , because the AR world wouldve propeled the whisper to greater levels of popularity and he wouldve gained much more business to boot. :confused:

So, which one would be more accurate/reliable from an AR action? Can the brass be made from .223 hulls?

Factory brass will be available soon.

Both are plenty accurate in an AR. The BLACKOUT just has a slightly different throat. Kinda like comparing a 5.56 chamber to a 223 chamber.

Just like the whisper, 300 BLACKOUT brass can be made from 223/5.56 brass. I have many thousands of pcs for people this past year.
