I call bullshit
you might get no measurable improvement in muzzle velocity, but I find it VERY hard to believe you would lose muzzle velocity
.44MAG lever gun chronos faster as SBR than a Carbine
for that to happen, the pressure from the atmosphere outside would have to be higher than that inside barrel
there's friction from the barrel, you know
Now if you were to up that to a 20" plus barrel it would really lose the MV
14" to 16.5" will cause about 10 to 20% depending on the powder,
yeah but that requires an insane scenario where the barrel friction is equal to or greater than the pressure difference between a figurative gunpowder explosion and NTP
you have no idea how high friction gets at near-sonic speeds gets do you
But if you go to a slow burn powder it will result in the traditional increased MV in up to 18" barrel
a simple way to visualize this:
does a 20'' have a muzzle flame?
Firing .45? I'm gonna say no
actually no, that doesn't actually prove anything
as what you're firing might burn VERY slowly
I can't find a 20" barrel i .45ACP
THAT is a good argument in my favor
Makes sense, why the hell would you do that
since you can't find a 20¨ barrel, do you agree it could be because a 20¨ barrel provides no benefit?
20" is a fairly normal "Rifle Length" Barrel across calibers
The M16s have 20" barrels, 20" shotgun barrels, ect
I have found 16 to 17" barrels for .45ACP, but then again the military chose 10" barrels for their Thompsons.
which one is optimal
obviously, if you use a 200¨ barrel you will lose out
but I'm
really interested to hear what the breaking point is
assuming
>20" is a fairly normal "Rifle Length" Barrel across calibers
I'd hazard a guess and say 20" is close to optimal since weapon designers have a LOT of practice
I mean it could be 16" as has been mentioned ITT
or maybe it's 24 or 22
in (7.62x51 Winchester Comercial loads) 24" is considered the best ballance of mobility vs Maximizing performance, in 6.5 Creedmore I hear calls for 26"
But in terms of usefulness, 20" offers a ballance of MV and functional mobility so it is common, the other big ones in the US are 16" because of the NFA and 14" for 5.56x45 rounds because that is the threshhold for useful MV vs FM that the military uses
The M1 Garand was set up with a 24" barrel
Lol
oh shit @Zuihou you play Girls Frontline?
i used to play it but it never gave me any of the guns i wanted so now i'm playing the game with boats
Azure Lane?
@Lagomaster24 yes?
Im in the GFL server
