View Full Version : Animosity among calibers

I've noticed in perusing Arfcom that there is not a small rivalry/animosity between supporters of the 300 Whisper/Blackout and of the 6.8 Rem. SPC.

I happen to really like both cartridges and see them as purposed and useful for two different (though occassionally overlapping) applications. I see the 300 as the ideal short-barrelled and/or suppressed assault rifle cartridge. So, for special ops teams who need quiet precision fire combined with the flexibility of a useful 300m assault carbine (when not suppressed), or for maximum utility (terminal ballistics) out of a super-short-barrelled carbine/SMG (such as the Mk.18) for non-spec ops personnel, such as vessel boarding teams, armored crews, house-clearing, etc. I see the 6.8 SPC as an ideal full-sized or carbine (anything with a barrel 14.5" or longer) assault rifle cartridge with superior ballistics to the 223 without all the weight, recoil, and need for larger-framed rifles as the 308 would require. The 300 is maximized in a 10-12" barrelled SMG/Carbine while the 6.8 reaches its ideal at 16-18".

So, I think these cartridges compliment each other and rarely cross over to competing with one another. Is the animosity simply because they are the only two real (SAAMI-approved) alternatives to the .223, and there is a sense of competition for survival, or is it just childish/un-reasoned rivalry?

I have not seen a single 300BLK fan say a disparaging word about the 6.8. I HAVE seen a number of 6.8 fans post mis/dis information about the 300BLK and post 6.8 numbers without equal variables (like barrel length, chamber pressures, etc) In fact, I believe one person was banned for falsely claiming that Travis Haley was paid by AAC to promote the 300BLK. He was not - he just likes the round.

In my reading, the overall "nastiness" has been one sided.

It would make a kickass subsonic only ak round for a intergal ak. Would have to use a standard mag and I dunno if it would feed correctly.

...... goes through an AR like corn through the Christmas goose using a grendel mag. Bullet weights from 180 to 350 gr and you gain some efficiency over the BR case? Nothin' not to be happy about..... 'cept it wont go through a 9mm suppressor :frown:

Spook,

Looks interesting ... but ... Get Thee behind me, Satan!!!!

I already have two 6,8s, two BLKs, a Spectre in process, a 416 Aagaard and a 416 Rigby ... I do NOT need yet another .416!
