Missing whole point WHY that cartridge was developed.
For actual battle capable weaponry there is no comparison with a 30-30 lever to a 30 cal AR with a 30rd or 40rd mag.???
They cannot be compared(different uses) if that was the case the 30-30 lever would be obselete because a 7mm mag has as much or more "getting it" at 400yds
![Laughing :lol:](./images/smilies/icon_lol.gif)
than a 30-30 at the muzzle (totally different application)though of those two if one has to get tossed(bye-bye 30-30)
Why a 300BLK----------------------220grain with it being supressed and at suburban combat distance and proper bullet=(bad guy down)
Create a reliable compact 30-cal solution for AR platform
Utilize existing inventory magazines while retaining their full capacity
Create the optimal platform for sound and flash suppressed fire
Create compatible supersonic ammo that matches 7.62×39mm ballistics
Provide the ability to penetrate barriers with high-mass projectiles
Provide all capabilities in a lightweight, durable, low recoiling package
Meeting these goals allowed the development team to negate many of the perceived drawbacks inherent to other large caliber cartridges when used in the M4 platform. Colt Firearms and other arms makers had previously chambered AR pattern rifles and carbines in various 30 caliber rounds but several issues were encountered. In the case of the 7.62×39mm, its relatively severe case angle caused feeding issues[4] unless specially modified AK47 magazines were used and even then results were less than outstanding. Modified bolts were also needed owing to its larger case head diameter. Rounds such as the 6.8spc and 6.5 Grendel had similar part-interchangeability issues but did allow for the use of the standard M4/M16 30 round magazine albeit with a reduced capacity.
Also keeping the M4 in mind as the primary host during load development the designers were able to work up a host of cartridges that would satisfy not only the ballistic requirements set forth but also ensure mechanical reliability with the fewest changes to the weapon itself with only a simple barrel change being necessary for a complete conversion.
For myself-----it loaded with the 30cal 220gr@1000fps in a tiny little 16" carbine that can pop off 30rds quietly in a few seconds=====KEEPER!
I have to say(I am new to this short carbine stuff) and say these short rounds(especially in the pistol cartridges)there is a vast difference.
I mean the carrying/handling/shooting and most importantly the speed at which the gun cycles.(you wouldn't think it is much but it is huge.)Example: Shooting my 20" barreled .223 Colt HBAR pull the trigger and you have this (now to me, long piiiiiiiiiiiiinnnnnnnnnnggggg sound combined with its action movement) use to think that gun was fast
Now shoot a 9mm or 40S&W in a carbine.(at least the Kel-Tec)there is nothing(its done)
As soon as you can rapid tap your trigger finger the gun is firing and I mean staying on target.
Honestly, I had no idea how much different.
Truthfully, I used to think carbines were a joke! Just a less effective machine.
Now I understand--------I had it wrong cause I was missing the concept entirely.
I get it now-----------better late than never.(just try one)
