Wow, that AMT must be worth a decent amount.
Very nice. Haven’t seen one of those for a long time.
Can’t use straight walled cases in a semi auto.
“Can’t use straight walled cases in a semi auto.”
At the risk of sounding naïve, what constitutes a straight-walled case?
“.357 would be much more practical.”
In terms of ammo availability yes, but not in terms of functional reliability. Rims complicate reliable operation in semi/full auto weapons. If your life depends on reliability, you want rimless.
Stupid.
A .45 seems more effective tactically than this goofy thing...
Sorry sparky. a 300 ain’t a 7.62x39. Much weaker. 30 carbine and 300 are no different. And the SD of a 110gr is better than your 100.
True. Good point and the most important.
Muzzle velocity will drop from around 1900 fps to 1300 to 1500 fps with 110 gr ball ammo. Still an effective fifteen or thirty round tool for home defense. ... Would make nice SBR when the collapse arrives. Choate makes a nice pistol-grip stock for the M1 carbines. I wonder if the gas port has been sized properly, since dwell time will be reduced by shortening the barrel?
.30 cal of the M1 Carbine most likely. Straight cased bullets a bit more guts than the .357 pistol cartridges.
M1 Carbines were popular in Nam because the M-16s were such shyt. The M1C cartridge is not very powerful but those M2 Carbines would fire all day long. My distaste for the M-16 lingers on to the point where I opted for a Mini-14 as my “assault weapon”. Yes, I know the M-16s are much improved today, but I just can’t overcome the bad taste in my mouth.
privy Partisan still makes both the ball and soft lead point rounds. I stock it for the Rockola I shoot.
But .357 is rimmed...
Muzzle flash = wasted energy
If you look at cartridges you’ll see that your .357 cartridge has a side profile that’s perpendicular to the base. If you look at a 30-06 it has a taper from bottom to top. The taper allows for easier extraction. 22 cal gets away with a straight case because it’s lightly powered and has a short case. A long case like a .357 is going to stick in the firing chamber and be harder to extract. There may be exceptions to this but it’s a good general rule. The M1C case has a slight taper. It’s also very difficult to reload and get to operate properly. Best to use only new ammo in an M1 Carbine. Also since the weapon was designed to handle M1C ammo it might be unwise to put ammo as powerful as .357 through it.
you identified the problem. I had a Universal Enforcer; which is basically the same weapon. It was reliable and very accurate, but because it does not have a buttstock, it was only useful when I propped it up with something. Basically, it was a toy.
Not sure how you knew I was in the Signal Corps, am a EE, and a ham operator, but thanks, I do always appreciate being called “Sparky”.
Sorry the 100 grn thing was a typo, I meant 110 and should have just said “the same” as I was intending to discuss the velocity difference for the same bullet weight.
I looked it up on the Hornady web site and it looks like a 110 spitzer bullet like in a 300 blk and a 110 grn round nose like in a 30 carbine have the same SD. But the spitzer bullet has a BC of .305 compared to .178 for the RN. Maybe not important for home defense, FISH (fighting in someones house) or whatever this “pistol” would be for, but just in general, I like having more BC to retain velocity longer and buck the wind better.
The classic 7.62X39 shoots a 123 grn SPITZER bullte at 2400 fps. So, since 300 blk only gets 2200 for the same bullet (see, I said “same” that time) it’s got a bit less power than 7.62X39. But, I would stay 300 blk is still more similar to 7.62X39 than to something that shoots 110 grn round noses at 2000 fps.
30 carbine has very few loads, the brass costs 2X as much as 300blk brass even if you buy 300blk brass instead of making it from 5.56. And 300 blk runs full capacity out of an unmodified AR magazine. Leading us back to the original discussion, I wouldn’t buy that thing, I would rather build an AR pistol.
Okay, I see. I was thinking that I have a semi-auto .44 Magnum and that case has straight walls, but it also has a rim at the bottom which might make it more extractable to a semi.
Good to know it’s still available.
I need one for the collection. Money is tight though, so it’ll have to wait.
Yes, discussed earlier up thread.
