Gotta compare "apples to apples".
Just happen to have all the guns named but my MG is a .41...
On a digital Postal Scale:
S&W 657 MG: 40.5 oz
Ruger GP-100 10mm: 37.4 oz
Taurus Tracker Stainless Steel: 35.0 oz
Taurus Titanium Tracker: 24.3 oz
S&W 686-7 PC: 36.7 oz (.38 Super with a 1/2 lug barrel. The standard 4" .357 full underlug is 41.3 oz)
Actual velocities from a 4" barrel with factory ammo:
.41 Magnum:
Federal VS 180 Barnes: 1304
Speer 210 GD HP: 1185
Winchester 240 PT: 1166
CorBon 170: 1273
Winchester ST 170: 1202
Federal Fusion 210: 1280
Remington 170 JHP: 1365
Remington 210 SP: 1247
Federal 210 JHP: 1266
Remington 210 LSWC: 927
Winchester 210 LSW: 960
Length from breechface to muzzle:
1911 GM: 5"
1911 Commander: 4.25"
S&W 657 MG: 5.75"
Ruger GP-100: 5.75"
Taurus Tracker: 5.6"
The nominal grain weight for a .41 Magnum is 210 grains... Sectional Density wise that would be the same as a 200 grain .40 caliber bullet. I just have one handload for a 200 grain bullet but it is running 1210 fps from a 4.25" Commander length barrel...so probably add another 30-40 fps for a 5".
If you watched the movie above he chronographed ammo from the GP-100 and 5" 1911..
Underwood 135:
GP-100: 1540
1911: 1600
Underwood 200:
GP-100: 1210
1911 (Underwood data): 1250
SIG 180:
GP-100: 1215
1911 (Underwood data): 1250
So looking at all the data, if you can run a 200 grain .401 at over 1200 fps from a 4" revolver and factory 210 .410s are only going 30-60 fps faster, you really think that someone/something hit with bullets of equal construction is going to know the difference?
Applying your .40 S&W logic to .357 Magnums...why would people want to shoot .38 Short&Weak out of a "heavy" .357....cheaper ammo and lower recoil maybe...
And if you can shoot 50 rounds of 250 grain/1265 fps loads out of your 24 oz. Titanium Tracker, God bless you...I am getting 1309 from a 4.25" FA 97 and no way I would touch off that load in a TI Tracker...
It isn't that a 10mm revolver is "equal" to a .41 as a .41 can run bullets up to 300 grains but the 10mm tops out at about 220. But to me this is great mid-caliber/mid-frame combination...
