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?

Thats what gets my vote.

It's ar15.com, what do you expect?:cool:

I think I'm seeing a pattern here... :wink:

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.

here's another one they can argue about

.416C ....450 grains of jacketed joy steaming down range at 1080 FPS :grin:

shot subsonic to 500 meters with VERY sub moa accuracy. :eek:

Spook, is that one in the middle a 9x39?

.375 so no,there is shit for bullet selection for the .355/ 9mm in the USA .

...only 20 thousandths difference so it might as well be ?

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:

Pretty close guess for my old, Mk.1 eyeball, eh? :grin:

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!
