The only blue part of VA :(

I know they have different purposes and are not very similar in form or function but i'm really on the fence here. you cant legally hunt deer with a 223 in Va and i would like to use the AR for some hunting.

i'm torn between the 300 whisper and 6.8 uppers. I've wanted a whisper for years cause i like suppressed rounds and my buddy had one that was pretty good out to 100-150yrds subsonic and 200-300 if you loaded it super.

anyone have/use/reload for both the 300 and 6.8?

plus...its a great excuse to get a 30 cal can.

Re: 300 whisper vs 6.8?

honestly, i can think of an area of Va i've hunted in where i've even had 150 yrd shots.

i'm mostly wondering about the effectiveness of supersonic 300 whisper/fireball vs 6.8 rounds for hunting deer. ideally i'd get both but $$ dont allow.

if its close to a wash i'll go with the 300 whisper and chuck 200+ gr lead subsonically through a can or load it up to supersonic.

6.8 has about an 8% advantage in energy from a 16 inch barrel. 300 AAC BLACKOUT uses normal magazines with 30 rounds capacity and uses a normal 5.56mm bolt. 300 AAC BLACKOUT will have lower price practice ammo due out in a few weeks.

I definitely like the direction of the 300 AAC with the practice ammo. Something the 6.8 manufacturers still haven't gotten after 6 years and the main reason I dumped the 6.8.

Re: 300 whisper vs 6.8?

the ability to use everything I have for my 5.56 guns except the barrel really pushes me in the direction of the 300 blackout . plus i reload and have a ton of 308 diameter bullets. all that being said I believe at the end of the day the 6.8 will be the better medium range cartridge for deer and pigs.

Re: 300 whisper vs 6.8?

I hunt in VA with a 6.8mm as my main hunting round. I use a Barnes TTSX 95 GR bullet and load it with 28.5 RE-10X. I have shot many a Virgina deer with a 6.8mm load and have not had an issue to date. I have not shot a 300 Whisper so I can't comment on its utility as a deer round.

The 6.8mm can be expensive but that is why started to reload for it. My practice rounds are 90 TNT's which are very accurate out of my LWRC 6.8mm.

Pretty much.

You mean JD Jones from SSK. AA doesn't build "Whispers", but Grendel and Beowulf

Paul, I am surprised to see that you dropped the 6.8mm. When I started going to the 6.8mm you and HTR707 were the guys I looked to for information on the round.

If things change, such as cheaper amo and cheaper plinking bullets, I may get back into it. All of the bullcrap with the 6.8 and all the bullcrap on 68forums (AR15Performance storefront) has left a bad taste in my mouth. I still think it is the best round in the AR15 platform.

Yes, they have been for sale since Sept 29th. Uppers are sold out for a bit, but some dealers may have some. AAC still has Model 700 and Model 7 barrels.

Re: 300 whisper vs 6.8?

ouch. $1100 bucks for an upper is a little steep for me when the only change from a 556 upper is the barrel. What kind of barrels do you use? WOW... as i typed this i came across the price of the Knights URX rail you use. $500 for the rail. no wonder.
wink.gif


i think i'm looking for more of a hunting/shooter grade since the useful range seems to be relatively limited on the 300BLK/Whisper rnds anyhow. And certainly with not so high end of a rail system...

EDITED: wasnt meant to bash your price, i was just surprised

Re: 300 whisper vs 6.8?

AAC uppers are higher end and designed for the military - KAC URX rail, nitrided barrel, BLACKOUT flash suppressor, high-end bolt carrier assembly parts (Carpenter 158 bolt), etc. There will be commercial grade stuff for sale from plenty of companies soon enough.

Re: 300 whisper vs 6.8?

This is a really interesting question regarding ballistics.

If you go with the .300 W/.300AAC you can put more energy on target.

If you go with the 6.8 SPC you can get a flatter trajectory.

But, if you go with the 6.5 Grendel you could have a 1k round in an AR15.

Each of these has advantages and drawbacks. With the .300 you don't have to change magazines and bolt. That's a couple hundred dollars. You can also <span style="text-decoration: underline">make</span> brass from .223 It's not hard. And the stuff lasts a long time. And, you get the most energy. Also, one thing to think about. Even though it may have a rainbow of a trajectory, this round is fully capable of reaching 500 yds. accurately. Silhouette shooters do it all the time.

With the 6.8 SPC you can buy off the shelf ammo. I've seen it in many stores out west and here in the midwest. You get a flatter trajectory, and enough power to kill a deer at reasonably long ranges, like about 400 yds. The drawbacks are you have to change mags and bolt ($100.00's). Brass isn't too expensive right now so that isn't too much of an issue. The other thing is you don't really have any means of going really long if you want to.

With the 6.5, you get bullets that can get you out to 1k supersonic. Contrary to popular belief, the 6.5 and 6.8 have almost exactly the same power capacity. It's just that you can fit a long range bullet into a 6.5 case where you can't in the 6.8. And they make long range bullets in 6.5, they don't in 6.8. But, for hunting bullets, you would get almost the same trajectory at the same ranges you would shoot a deer with the 6.8. Without the 'super' bullets the two become almost one in the same. The drawbacks of the 6.5 are hard to get ammo, if you don't reload. And even components are comparitively expensive. 100 Hornady brass is $66.00, Lapua is $96.00 AA is $75 and 7.62 brass that you can form is $40.00. Unless you can find a ready source of 7.62 'once-fired' this is spendy.

Comparing that (super bullets) to what you can shoot from the whisper and I think you still end up unable to shoot out to 1k. That is if you ever desire to. It may never be an issue, but just a thought. For the .300 a 300 yard shot with a 125 gr. bullet will drop about 5 feet. But zeroed at 175, the .300 shoots flat enough to not have to hold within 200 yds.

-hope that helps

Re: 300 whisper vs 6.8?

interesting. im not really interested in the 6.5 though. i dont see any benefit for me. i mean, i have a LR gun but nowhere to shoot over 2-300 anymore.
smile.gif


but i do love quiet. and i remember my buddies 300 whisper sounding like an airhose getting disconnected.
wink.gif


i'm leaning towards the 300... just need to find either a cheaper alternative for the 300BLK or if the whisper barrels can shoot the BLK w/out issue
 
#25
Re: 300 whisper vs 6.8?

I'd go with the 300 Whisper/300 Blackout.

You can form your brass from 1X 5.56 brass, can't get cheaper than that without going steel cased.
You can use USGI mags.

Hunting you can use a 130 TTSX, 125 Nosler supersonic or a 200-220 subsonic.

Re: 300 whisper vs 6.8?

thank you. now, can an older 300 whisper upper shoot the "new" 300BLK rounds or is that something you cannot answer?

i think I read over at silencertalk that the reamers were veeeerrrry close between the 300/221 fireball, whisper, and BLK.

Re: 300 whisper vs 6.8?

They were talking about this on Quarterbore forum , in the 300 Whisper section . If I am not mistaken , the main difference was neck length . There are several builders of 300/223 over there who could answer your questions . AKA-SPOOK here at SH could probably give you the info you are looking for . I had 300/223 he built and really liked it alot .

Re: 300 whisper vs 6.8?

I shoot the 6.8. Ive got to say it is a great round to hunt with and while ammo isnt cheap like 223 its still not unreasonable, even better if you reload. You can find brass and die just about anywhere. I can find ammo from 17.89-19.99 a box. This really isnt bad.

Ive heard of guys shooting it reliably and accurately out to 600+ yards.

It is a versital round for hunting and home defense. While I dont see the military ever changeing to this round, I do see it gaining in popularity. Hopefully one day the ammo will come down in price with a good plinking round.
