6.8 vs 300 blk- which will win?

[mif_slim]

Pryde, thats too much / =....

[w210838]

I don't think the 6.8 is dying or dead? A lot of people love it and shoot it. I know people are going to say you need special parts for it to work but isn't that the beauty of the ar? It's the Legos of guns. When I think of dead/dying cartridges I think of my pre 64 in 300 h&h or my model 94 in 348 Winchester , those are old dead cartridges. My .02

No way! Bravo Sierra! Cheapest I can load 5.56 is (with 4 yo components when they were cheap) is: Projectile= .067ea Primer=.015 Powder=.055 Brass=.015 (5x reloading per case) Total=.152ea or 152/k. Todays prices would be triple that price!

The fact that you obviously didn't get the joke indicates that you are indeed a worthy candidate of being belittled.

Let's explain this for you Barney style:
45GAP / 6.8SPC = both dead/dying cartidges

He cast his own bullets for free, and his brass is free. Powder cost are way less per round because he is loading subsonic.

Re-run your numbers with free bullets and free brass...

[dfletcher]

well I get the lead for free...
alliant 2400 is $147 shipped plus hazmat
primers were 36 per thousand
brass is free...

I reload for the AAC too, couple of different rifles actually. My AAC is a Remington 700 SPS with 16" threaded barrel, a friend has an AR. I'm interested in how the lead does in the AR - any issues with the gas port being crudded up? Reliable?

I lean toward 125 grain jacketed @ about 2,200 fps but the AR shooter likes "slow & heavy". I like the round as a "plinker" out to about 100 yds, is just a pleasant fun little cartridge. Were we in a state that allowed silencers and SBRs an AAC shorty with a Surefire shooting heavy bullets would be a great home defense gun.

Love how some guys say something like your first paragraph and then fall back to the joke card. Nice. But then I just saw that you didn’t say the guy was wise, just wiser than you. It’s all relevant. That’s a joke (albeit bad).

This guy still doesn't get the joke I see. Keep digging, you are making quite the spectacle of yourself.

Btw, what military units are using the 6.8?
I heard the 11th Pink Unicorn Cavalry has been issuing it to use in the war in imagination land.....
I think their sidearms are chambered in .41ae

[dfletcher]

I find most cartridges interesting or useful in some way, but it occurs to me that a contest over "AAC vs SPC" is like arguing who was prettier - Totie Fields or Mama Cass.

I'll pause so anyone under the age of 50 can google and return .........



It seems to me these two cartridges are so different that comparing on merit really can't happen. As to which one "survives" with .00003% of the AR market - probably the AAC, simply because it uses a 30 caliber bullet.

Not making a spectacle. Just calling a spade a spade.

BTW, Jordan and Saudi Arabia are currently using the 6.8. I never knew they had a Pink Unicorn Cavalry.

I agree completely and this is what most people have been saying all along. .300 isn't "all that" and will never replace .223 for military use. However it will last in terms of longevity simply due to the ease of finding materials and parts.

6.8 fans love to turn any alternative caliber discussion into a debate about how their favorite obsolete round (that is totally NOT dying) is ballistically superior to all others.

300 blk = .308 bullets, .223 case, make your own.
6.5 = .264 bullets (very common), 7.62x39 brass (admittedly less common than steel), make your own.

6.8 = all proprietary

[BigART71]

This is all interesting..

I find myself thinking of a new upper for hunting pig and deer.

I have no experience with the 6.5, 6.8 or 300BLK.

I don't need anything past 200 yards because, for me, that shot is rare in Northern Ca. If I plan on taking a shot past that I'll bring my trusty 700 BDL in .30-06 <-- I love this caliber, but my rifle is way too HEAVY for hunting.

In trolling through tons of posts on several forums I find myself leaning towards these factors:

1. availability of ammo

2. do they have Barnes - because I'm in Commifornia and I need lead free for hunting now

3. how easy is it to change setups, i.e. how many parts must be bought and replaced?

4. cost... i'll probably need 2 of everything because my wife also wants to go hunting with me and she also has an AR 15.

I thought about accuracy out to further distances, but in all honesty it's not likely for me. The longest range near me is 200 yards and is only available Friday mornings from 10AM-12PM, so that stumps the practicing at really long range beyond 200 yards.

This makes me lean heavily to the 300 BLK. I can get the upper and ammo and be done.

I haven't made up my mind on anything, but that's my thoughts for now.
