brad cole 65 Posted August 30, 2013 Report Share Posted August 30, 2013 (edited) A few questions for anyone who has a 300 aac. Does it perform reliably? are you happy with the performance of this round so far? and any likes or dislikes of this cartridge? what is felt recoil like etc? any info is appreciated. I have read a little about this round but I trust your responces more than most. Thank you to all who respond. I meant 300 AAC in the title oops Edited August 30, 2013 by shankkole Quote Link to post Share on other sites
gunfun 3,931 Posted August 30, 2013 Report Share Posted August 30, 2013 I don't own one, but it is the plan. I really liked the one I got to shoot, owned by a member here. Very smooth. The recoil with subsonics and a can felt like shooting a smooth AR in .223. It was easily hearing safe, and the cast bullets he was loading into trimmed .223 were costing little over the price of the primer. If you use pistol powders and have free range scrap, cost is probably less than $.05/round for 230 grain 1100 FPS ish ammo. 2 Quote Link to post Share on other sites
brad cole 65 Posted August 30, 2013 Author Report Share Posted August 30, 2013 awesome thanks really liking the idea of a harder hitting AR with standard mags and internals.and the subsonic /can abilities Quote Link to post Share on other sites
gunfun 3,931 Posted August 30, 2013 Report Share Posted August 30, 2013 IMO it makes sense for a reloader but would be too expensive to shoot if you are buying ammo. For factory ammo, just stick with .223. Quote Link to post Share on other sites
brad cole 65 Posted August 30, 2013 Author Report Share Posted August 30, 2013 everything I shoot I smelt ,pour, swage and load myself. I couldn't afford this pastime if not and you appreciate each round a little more that way. at least thats my 2 cents Quote Link to post Share on other sites

sccritterkiller 473 Posted August 30, 2013 Report Share Posted August 30, 2013 I'm intrested to see the responses to this thread...I have shot them a few times with and without a can. Fun to shoot with a can but what isn't. Didn't notice anything different in the recoil than a standard 556. We didn't have any feeding problems either. The biggest issues we had was the difference between sub and no sub on target, which is to be expected. I currently have a complete lower and all upper parts minus the barrel to build one up. I just don't know if I want another caliber in my inventory. I don't reload so for the reasons stated above I thinking of just doing another 6.8. I love that round for hunting.

SwissyJim 117 Posted August 30, 2013 Report Share Posted August 30, 2013 Also have shot one a buddy has, and LOVE it. very little muzzle rise - much MUCH better than my .308 (duh) and at least as good, if not better, than my .223. Like it so much I am putting one together myself from the ground up - already have 2k brass ready for reloading. Also read somewhere a number of 3gun people are going to it, since a mere scrape on a target will trigger a hit, vs a .223 that will not. But since I believe everything I read on the Intertubes, I have no reason to doubt that Oh... and mine will be a SBR, most likely in the 10" range. Quote Link to post Share on other sites
gunfun 3,931 Posted August 30, 2013 Report Share Posted August 30, 2013 AAC's sight said something about the 3 gun championship being won with it. I am sure it doesn't have the long range trajectory of .223, but with high velocity ammo, it would be less susceptible to wind drift, and would hit steel harder for poppers and the like.

sccritterkiller 473 Posted August 31, 2013 Report Share Posted August 31, 2013 I have read a couple different places that the ballistics of the sub 300 aac and a .45 acp are really close. I would assume that an sbr would not help the 300 any. I would consider neither a option for hunting..I guess that's why I still have a drawer full of parts... Quote Link to post Share on other sites
Sdustin 578 Posted August 31, 2013 Report Share Posted August 31, 2013 Its shoots fine at distance if you can get your hold over right. I own an aac 9 inch it has more blast and recoil than a 16 inch midlength in 556. I really like but it really is a bad time to try to buy factory ammo. Also with reloads you really have to get them accurate because the MV Standard deviation with throw you way off at 500 yards. A difference of 50 FPS could mean missing by feet. I say if you cast and reload its no question you need this caliber unless you like the ak platform cause then you should just buy an ak. 762x39 is about the same thing only the blackout works in an ar better. Also if you cut down 556 cases you will need to anneal because you cut the part of the case that was annealed at the factory. I had very poor bullet tension on lots of the first cases I did. I annealed them and sized them again and that went away. Critterkiller would you consider the 30-30 a no go for hunting. And im guessing you in south Carolina id say a 300 blk would be a fine choice for hunting anything you have in your area. Quote Link to post Share on other sites
sccritterkiller 473 Posted August 31, 2013 Report Share Posted August 31, 2013 (edited) 30-30 wouldn't be my choice for hunting either...I hunt a lot of ag fields so shots out to 300 yds are possible...You forgetting about the big hogs...300+ lbs. Saw a guy few weeks ago drop a 320 lb boar @ 80 yds with a 30-06 180 gr corelock. Hit it behind the ear no exit wound. Those big boys are tanks.

mostholycerebus 415 Posted August 31, 2013 Report Share Posted August 31, 2013 I really like the x39, which is why I am building a couple of 300BLK's. Its basically identical ballistics, but has many, many modern bullets available. I feel x39 has more potential, but cheap steel-cased russian import ammo keeps good companies from jumping in that market. Something like a Barnes TAC-TX with a round/charge developed for the case capacity of x39, and I would sell off my 300BLKs. Well, maybe. The 'Mens Lego' factor is kinda fun too. 1 Quote Link to post Share on other sites
XD45 7,124 Posted August 31, 2013 Report Share Posted August 31, 2013 (edited) I am seriously skeptical about "better" cartridges but this one has serious advantages. I have never liked a 22 bullet for anything bigger than a coyote. Saying that sub 300blk hits no harder than a 45acp is somewhat pointless since sub loads are special purpose. The standard 300blk loads have excellent ballistics for an AR platform. I prefer my rifle bullets in 0.30" and my pistol bullets in 0.45". A 300blk upper is on my list. I predict the commercial ammo availability/price will improve soon. Edited August 31, 2013 by Darth Saigus Quote Link to post Share on other sites
RedChallenger 149 Posted September 1, 2013 Report Share Posted September 1, 2013 I'm shooting 300BO suppressed and absolutely love it. I am reloading it and using cut/sized (free) .223 brass. It is a awesome round especially subsonic. Quote Link to post Share on other sites
saltydecimator 482 Posted September 1, 2013 Report Share Posted September 1, 2013 finally a pic!!!! goin to pick me up a core 15 barrel tomorrow. ya go for it its alotta fun... not the same accuracy as 556 but its definietly cheaper and quieter Quote Link to post Share on other sites
FORKLIFT352 63 Posted September 1, 2013 Report Share Posted September 1, 2013 I got a 9in. barrel 300 blk..it's in pistol configuration. Someday I'll get it papered... Most of my reloads are between 130gr and 150gr supersonic... 200 yards right on target.. The difference is like .40s&w ( snappy) and .45acp (push) From my understanding the difference between say a 9 in barrel and 16 is 100/150 fps and accuracy is negligible... I love the versatility even though I haven't gone subsonic... yet. 1 Quote Link to post Share on other sites
brad cole 65 Posted September 1, 2013 Author Report Share Posted September 1, 2013 thanks for your insight. I am looking forward to purchasing and shooting my own 300 very soon. The only negatives I hear is WHY? or NOT A BIG DIFFERENCE? but I can see possibilities for me personally with this round. Quote Link to post Share on other sites
RedChallenger 149 Posted September 1, 2013 Report Share Posted September 1, 2013 (edited) Here is a much better pic. 10.5 with pistol length gas port. Just had to buy the barrel, gas block and hand guard as I had the other parts (upper, bcg, etc) already. Gotta feed the machine Edited September 1, 2013 by RedChallenger 1 Quote Link to post Share on other sites

filthygovemploye 64 Posted September 3, 2013 Report Share Posted September 3, 2013 shot some bent cast 230 grs at a hundred yards, pistol config with red dot. thats the only time i hit steel was with a failed bullet... Quote Link to post Share on other sites

Spacehog 2,218 Posted September 4, 2013 Report Share Posted September 4, 2013 I just recently built one. I used a spikes lower, DPMS LPK, and AAC 12.5" complete upper that was on sale. It is currently in pistol configuration until the tax stamp for the SBR and AAC Suppressor comes in. Total build cost with parts I already had was about $950, although there are cheaper options with just a barrel swap out there. IMHO this caliber is a reloader's dream. Supersonic loads are on par with 7.62/39. Suppressed loads are very mild with regards to recoil. The answer to the question "Why this when you can just shoot 7.62x39" is the versatility of different loading options. The ability to use standard 5.56 parts and magazines for rifle maintenance over time is also a big plus for me. The only draw back at this time is the availability/price of factory ammunition and the premium upcharge on the barrel over a standard 5.56. I think this will change with time. If not I have plenty of 5.56 brass that I can cut down, size and reload. I reload .308 already so I have a ready supply of 150 gr plinking rounds up to 208 gr AMAX for subsonics. To get started I bought 500 rounds of 147 gr 300 BLK from Freedom for $335. It was painful to pay that much, but I figure I can get at least 4-5 reloads out of them and I would save myself the work of cutting down and trimming the 5.56 cases. Plus the necks were already annealed unlike the cut down 5.56 cases. For me the difference in cost was worth the initial time and effort saved. 1 Quote Link to post Share on other sites

XD45 7,124 Posted September 6, 2013 Report Share Posted September 6, 2013 Best info on annealing I've seen: http://www.6mmbr.com/annealing.html I've seen some amazing setups for making 300blk brass using a dillon trimmer/sizer on a turret press. If you couple that with a carrousel annealer you could churn out perfect 300blk brass by the thousands. 2 Quote Link to post Share on other sites
gunfun 3,931 Posted September 7, 2013 Report Share Posted September 7, 2013 I have been toying at modding out a qwik trim to work like a ghetto dillon trimmer and do just that. other than cost, the advantage is that it deburrs while trimming. The other thing I have had in mind is buying a spare priming assembly and welding it up and reshaping to be an on-press primer pocket swager. This would be even simpler on a turret or single stage press. Upstroke forms the brass, downstroke uniforms the primer pocket... Quote Link to post Share on other sites
