I have yet to have a revolver fail. I have shot thousands of 40 rounds over the last 30 yrs. I have had semi autos jam double feed etc. As far as the 10mm room to load hotter. They have. To what avail? There are 40 loads listed at 1050 or higher. What does 150 fps and 20 grs of bullet weight get you? I have shot deer,pigs, even a cow. All cast lead at 1,000 fps or less. Trend is just put a bullet in the case for a gun not desigined for that bullet weight. Semi autos are tied to ammo and function.
I've had a couple of revolvers fail. All were ammo related.
I've got thousands of rds in USPSA matches, 3 Gun matches & steel plate matches. I used 3-4 different guns over the years, all were 100%.
Last I looked, pigs, cows & deer neither shoot back nor take cover behind steel doors or cars. Thugs do, which is where the 10mm shines with the extra HP.
Cor-bon shows their 165gr 10mm as follows:
- Muzzle Velocity: 1250 fps
- Muzzle Energy: 573 ft-lbs
Cor-bon shows their 165gr .40 as follows:
- Velocity: 1150 fps
- Energy: 485 ft-lbs
That's a pretty good leap in energy there, IMO. I'll take that when car windshields & other hard objects come into play.
The only one who can save MY life is ME. I'll take the 10mm, Alex......................
