300AAC Blk - Questions

[Brandon Sneed]

Before I stick my neck out on another board, and dispel any myths, I think it would be helpful to gain a little insight.

As a prostaffer, it is my job to assist in any misnomers or correct any misleadings or badmouthings about the company or its products.


Here's a few links. Little bit of reading material for you guys:

Now, I remember speaking to Carl about this caliber in depth almost a year ago. Saw that the new barrels were being offered. Since I hadn't had the cash flow to complete the .260REM that we briefly visited about in the past, I've instead worked on little projects (called having a child), and reading lots of material; I am a little concerned. I have been working so much to get things taken care of at the house that I hadn't had much time to get any AR projects finished (not to mention the fact that a few customers have kept my cash flow tied up with their own builds instead of mine!) As a result, I do not want to work on a project that will not benefit the buying public... Most folks in my area who buy an AR10/308 platform semi-auto are buying factory .308 or .243 from Remington or DPMS. Where I live, and folks whom I hunt with or shoot with competitively, the 300BLK is QUITE a bit more appealing and important than the .260 REM. .223Rem and 6.8/.264LBC are even more appealing than the .260REM... so the 260 has gone on the back burner yet again. Hopefully though, as a side note, this project will get finished, but I don't see it happening until after the First of the Year now. That being said, I can't steer them to a direction to a barrel manufacturer, unless I have solid proof that the company has a viable option (speaking of the .300AAC BLK at this point).


Most folks I have visited with about the caliber, want a SBR, will shoot both sub and supersonic. I would use it for supersonic use, with a standard 16" barrel, and a 9" barreled pistol. That being said, the above reading plays into the hunting situation FAR more than the aforementioned personal uses. The other group will shoot out of a 14-16" barrel, for hunting purposes. Hogs and Deer are the key down here, but Deer are not allowed to be hunted with a sound suppressor/silencer. SBRs, no problem.

The caliber, as noted by Remington and AAC for subsonic use, carbine gas systems were the extent of the length of gas system. Nothing LONGER than carbine for a reason: challenges with cycling ammo of all levels (supersonic, subsonic and transonic). I've done my research, however, I don't have a gun to shoot yet. I had a barrel from another manufacturer, as BHW had only 1/11" twist barrels at first. Since the new 8.5" barrels have come out, there's still speculation in the subsonic arena that there are issues.

Obviously this being a public forum, but designed for help and assistance in all areas BHW, I wanted to offer this up so we can brainstorm on how to assist the market in this caliber, and sell more barrels. LOTS of info out there is leading me to believe that the leaders are going to stay leaders, and this "wildcat" that has been submitted to SAAMI will not necessarily be the bread and butter of BHW. I know that's not the case anyway, currently, but wouldn't it be nice to have a greater share?


I know there's been some time spent on this caliber, but for me to do my job, at least on the internet, I have no way to help. My hands are tied at this point. I may be rambling, but any other prostaffer that has dealt with this caliber, please speak up?

I'm not on AR15.com much, except to browse usually, but I'm on SilencerTalk QUITE often. Some of the guys know me quite well from other forums, so they know I'm not stupid or a novice, but in this area, I'm a novice.



Oh.... on a side note..... there's a financial motive for me to start shooting this as well: www.silencertalk.com/forum/viewtopic.php?f=128&t=74305



Please advise what we should do to rectify some of the negative publicity here. I want to sell some barrels for you guys.

Tempted to suggest you stick with 1x8 spec for all 300BLK and start offering 7.62x40wt in 1x11.

I think the 1x11s will have difficulty stabilizing the standard factory 300BLK 220 grain subsonic ammo. You could end up with customers inadvertently damaging if not destroying suppressors. 300BLK chambers should be able to handle all factory 300BLK ammo including subs. Currently the 220 Remington subs and 208 AMAX subs by Hornady.

7.62x40wt has the same parts benefits as the 300BLK but was not intended to shoot subsonic. With a bit more case capacity it is intended to focus on lighter 30cal supers and would be a better choice for a reloader who intends to get a 14.5"+ barrel and hunt with it.

No barrel loss either as you can ream out all your 1x11 300BLKs into 7.62x40wt.

Hi,
In my opinion we need to look back in time and remember the original movement behind the 300 whisper.
I think the blackout has been oversold in supersonic but where it really shines is in the subsonic role and the versatility that this offers for many folks.
Many .308 win tactical systems come out geared with the standard 1:10 twit for tactical use but those are normally longer 18 or 20" barrels to stabilize the heaviest of the heavier bullets in both supersonic and subsonic loads so a 1:8 doesn't seem like a bad idea in SBR configuration.
I personally do not think that a 220gr is not going to kill anything better than a 210 bullet cannot kill. BC at this point might be more a determining factor along with bullet properties and terminal ballistics at subsonic speeds.
I think the 7.62x40wt is another very nice but a little oversold too in supersonic cartridge but I can understand why folks might find appealing beating up the AK in its own turf and with standard AR bolts and mags.
Therefore I think that the blackout will continue to be a nice value for those seeking a decent short to mid range compact hunting system with the advantages of being an very acceptable supersonic+ a very nice subsonic system all in one upper.
Regarding the gassing issues I think that this can be resolved with a self regulated gas system. I have a home made design that I need to yet perfect but that I believe will work with any caliber or load. It needs tuning and different springs but once done you are done you do not have to touch it again.
Alternatively one could try a piston with suppressed mode (ie: Adams) and tune that one with a can or brake system that allows tuning as well. I have seen brakes that you can hand toque / adjust for more or less pressure.

I think one first can test the barrel and loads while the gas port fine tuning can be workout later sometimes even on the field.

Cheers,
E.
