Why is there no "Thumper"?

6.8 is not a thumper but everything the 556 is plus more. The only drawback is ammo price then again most 556 owners don't shoot their rifles as often as they like.

Making ammo significantly more expensive, and less common, won't lead people to shoot more.
 
A short-barreled AR in .50 Beowulf, .458 SOCOM, or .450 Bushmaster fits the bill about perfectly.

Of course a lightweight, high velocity round like 5.56 is plenty effective, and has less recoil longer effective range, and higher capacity to boot, which makes more sense to me for the carbine/PDW role than a big heavy thumper round.
 
I seem to remember someone trying to sell an M1 Carbine converted to 45 Win mag,but the project never seemed to get out of the idea stage. My first thought was the 450 Bushmaster when I read the description.
 
What about a SBS converted saiga 12 with 20 round drum?

I don't know what Jeff Cooper would have made of it, but that's sure as hell a Thumper in my books! It will most certainly fall foul of the "lightweight" requirement however.
 
I think the Russian rifles name is VSS and it has a integral suppressor. Would be perfect as a hearing friendly thumper.

It's an interesting round but so far I haven't seen it in the flesh or seen much re. its performance. I did use it to good effect against mutants in STALKER, though ;-)
 
Without a can a rifle caliber cartridge in a short barrel rifle is a pretty terrible home defense weapon unless one believes a potential for disorientation during a defensive scenario is a good thing.
 
I'm kind of turned on by the idea of a .458 SOCOM in a suppressed SBR configuration. I've never shot one though, and can't comment on how well it shoots.

To me, this is the closest to Cooper's Thumper that I've seen.
 
.458 also recoils substantially out of the platform it was designed for. 12 gauge-like kick, albeit recoil is very subjective, out of a rifle as light as the AR-15 means you'd probably better hit what you aim at the first time, as you may not get fast enough follow up shots to hit again. I'll take that 556 please.

Have you shot one? Its not a 5.56 (and of course doesn't hit like one on the other end). It is far from uncontrollable or something that one cannot make follow up shots with. The ability to make follow ups is going to be mostly a matter of shooting technique. This is a beowulf but you get the idea. The guy in the video below doesn't appear to have anything approaching the worlds best technique and you'll note he is hardly being tossed around. It is not as fast as you'll see folks shooting a 5.56 but its not even as fast as you can shoot the big bores either.

For SD, general combat, and most things I'd gladly take 5.56 or if I wanted to step it up, I'd rather a 6.8 SPCII or a .308. However, if one is envisioning coopers "Thumper" these cartridges are closer to the 1800 FPS from a 10" barrel, optimistically to be had from a 44 auto mag, that Cooper wrote of. Cooper did call for a folding stock, so maybe one of the Sig 556 guns Tony Rumore converted to 458 SOCOM would be better (although I think that project was abandoned as I haven't heard anything about it in a long time). The SOCOM et al also tend to fail the 20 round box mag requirement.



Great pic but with 10 round mags you fail the high capacity test.

You just need this. It gives you 30 rounds BTW I am being factious so please don't waste time telling me all the reasons it is impractical. I know. I suppose a smaller drum, along the lines of the saiga 10 round drums could be made that wouldn't be so unwieldy and would offer a capacity increase. For tasks I'd use a .458 SOCOM for, I personally am content with 10 rounds.

Yes I have. My statement wasn't an opinion. Recoil is subjective, and to me there's better rounds for the HD role. Personally, I don't prefer a rifle for that cause indoors, but I like 556 for that purpose. I can fire it quickly, accurately, and if I'm already at a high stress level, I need those two things in order to save some bacon. The recoil of the 458 isn't bothersome physically, but I find it hard to connect for more than one shot. That's me, ymmv. Or maybe I suck, but not with 556.

How the gent in the video shoots has no bearing on how I shoot. He isn't being shot at, harassed, or threatened. His family isn't counting on making the hits count, and I'm going to blatantly assume he's not experiencing the stress issued from altercation. Stress, close quarters, possible darkness, and situational self awareness are things that come up in an HD scenario. I don't want to combat muzzle rise and target acquisition as well. In that case, the 556 "thumps" plenty for this shooter.:)

I have not, however, shot the .50 Beowulf. :(
 
.300 BLK Carbine

Naturally I would have a different sighting system. The scope on it now is for some accuracy testing. It can switch from AR to AR quickly.

I think that was Le Mag back in the '90s. IIRC, they also produced a .50AE version.
 
I'd rob a bag man for the mob, if I knew when and where he was, and if he was toting enough money. :) They don't scare me a bit. How the hell would they even know who to look for, in the first place? In the second place, I wouldn't do it for less than 1/2 million $, cause it's all about leave the US and change your face, any serious felony, and to do all that, I'd want enough money to retire upon, in the third world.
What the hell? Do you realize that you're on a firearms forum? Cocaine is a hell of a drug!
 
It's called a tactical shotgun. The problem with the .30 carbine was lack of effectiveness especially at more than 30 yards, same with shotgun. Not great for combat but best for home defense.
 
I don't disagree at all that on a balance 5.56 is better suited for HD than 458/50 beowulf etc. I wouldn't feel bad if all I had was a SOCOM, but I wouldn't replace my 5.56 guns with one for that purpose.

Not great for combat but best for home defense.

It is far from settled that a shotgun is "best" for HD. In fact, the only advantage a shotgun has over many other options is price and power. When talking "best" I give little weight to price, but I recognize for some it could be very important in what they can actually get. The power advantage of the shotgun also comes with several drawbacks.
