What do you guys think about this? I like the .300 Win Mag round and seeing it in this platform looked good, but I'm not sure about this one and haven't had time to thoroughly investigate, but I like the idea.

Any thoughts? Any better rifles in .300 Win Mag on a similar platform that you would choose first?

Doesn't do anything for me. If I was going to get a 300WM it would be in a bolt gun, but I can't envision me getting a 300WM any time soon.

i could see potential application for the military and LE snipers for extended range shots outside of 308 reach, but for a civilian use - limited to say the least.

Agreed. And match .308 gets pretty far out there. I had a chat with a retired SEAL sniper not too long ago, and he said that for the most part, bolt guns are out where he was in the .mil, because of the quality of the current semi-automatics. A gun like this, would fit that description - good for shots over the 10-1200 yd range after a .308 goes subsonic and tumbles, and semi-automatic for follow-up shots; but for a civilian, the extra accuracy of the bolt is worth more than making quick follow-up shots, at least imo.

Not necessarily, too many factors that play a role. A good analogy is the .308 is a tool for the job, but not the best tool when it gets to longer ranges.


Not as practical as a .300 or .338, but clearly doable.

There is a Winchester M70 in 300 Win Mag in the classifieds right now for $350. If I were thinking of that caliber, I'd buy it, shoot it a few dozen times, learn it's way too much for anything practical, and then sell it for not too much of a loss.
But that's just me.

Obviously, I was being kind of a smart-ass. However, In the hands of just about everybody except the very elite of the military sniper community, the .308 will do everything the 300 win mag will do. Now, if BIG game hunting is the intended use, the 300 is probably a better choice for the large bears, but that's about it. I'd have to have it in a bolt, though.

The AR chambered in 300 win mag? Sounds like a sales gimmick to me.

I'm not sure what you're disagreeing with me about, but implying one chart will map every .308 bullet at any velocity is not correct at all, according to the research I've done. My ballistics calculators have some of my higher BC bullets crossing Mach 1.2 at well over 800 yards, and at velocities that are well within high-pressure ranges. What is the source of that chart?

If you looked a little closer, you will see that chart is a complete joke. It was made because a lot of people assume a .308 can only go 800 or 1000 yards, and then it dies.

I'm not really disagreeing, just saying it depends on the situation. .308's can stay supersonic out to 1500+ yards, but that depends many factors.

Heh, right on. Sorry, I don't seem to be firing on all cylinders today. ;)
 
PatMcD, ha ha, I had a feeling that you were. I appreciate the input, and from everyone as well.

Let's be honest, that functionally this gun has a lot of questions, which is why I posted it. I've never fired the .300 win mag and although I've fired it's relatives I've heard that it packs quite a kick in comparison.

If we're going to talk accuracy well, the .300 Win Mag takes the cake, but as I suspected and accurately so, everyone is say bolt that puppy and that the AR platform is really not a good platform for it.

Also, we haven't even taken into account yet that this carbine is not MA compliant. Thanks to another friend for quickly pointing that out (and dashing my hopes and dreams! lol).

This is really just a fun gun and with fun I mean expensive!
 
The parameters for a .308 to stay supersonic to 1500 yards are pretty unique. 10,000 of altitude will do it though. [wink]

Or outer space, which is where a lot of NESers seem to be immigrating from lately.

You could just get a 6.5mm Grendel from Alexander arms and call it a day. As far as I know, it is just an upper, and uses the same magazines.

6.5 creedmor would be way better than 6.5 grendel if you are going for distance. Grendel would fit on an AR15 lower, but the creedmor will fit on an LR-308 lower.

I like the 300 win mag mostly because it's a caliber other than 308. The more calibers that come out for AR type rifles, the better.

When will they make one in .30-378 weatherby? Now that's a great long distance .30 round if you can afford the ammo.

Sorry, but that's just not true. Maybe the second part.

.308 stays supersonic past 1000 yards. This is a fact. Its effective range is a whole other thing. The USMC M118LR is known to have an effective range of around 1000 give or take weather otherwise they wouldn't use them seeing as the Scout Sniper qualification range is 1000 yards.

so whats your load data?

I don't have my own. I wish I reloaded or knew how, but I don't. I can get you more load data from more reliable places, but I'll need a few. The heavier rounds above 175 will have more drop but a higher BC.

Here's a thread I just googled to show you at 1350 this guys round goes transonic. I've seen other load data of people getting prettty damn close to 1500. Definitely not common but if the reloads are perfect and so is elevation + weather conditions, then it is possible.

Subsonic or supersonic? And either way nothing is just "fact". You can load a .308 in many different ways to make it stay supersonic or subsonic at 1000 yards.
 
ive seen that thread

His's went transonic at 1350, thats not 1500yds. All i saw from that thread was some boasts from other posters about 1660yds.

please post the load data you found i really wanna see it cause its probably nuts.

Try some M852 or Federal Match out of an M14 and let me know how that works at 1000 yards. It's well below supersonic at that range.

Irrelevant. Federal Match sucks, btw.

Berger 185gr HPBT (Litz), 2700fps muzzle velocity, and it's not that hard to go faster. I run these out of a stock 5R with no issue. Put that in a real barrel, and you'd see better performance - now, 1500yds with a .308, that'd be something. Though I've been testing the 175gr OTM Match boolits and haven't had a chance to see how they perform through the transsonic barrier - they are advertised to stay dynamically stable.
