7.62x25 equal to .40 smith &wesson?
Just wondering what you all would think about the 762 by 25 versus the 40 caliber smith and wesson. Is the 762 by 25 at least equal to the 40 smith and wesson in energy and velocity and that sort of thing? It certainly pounds harder then my smith and wesson m&p 9.
Is there a ballistics table that would compare the 2?

The only common pistol round further away from 7.62x25 than the .40 S&W would be the .45 ACP. The 7.62x25 weighs half as much and is much faster than the .40. Additionally, the 7.62x25 is about 75% the diameter of the .40. Consequently it has more energy and will have more penetration (or over-penetration) and a flatter trajectory. The 7.62x25 is about the only pistol round that can penetrate a Kevlar helmet. There are reasons that the 7.62x25 are no longer used by the Russians and the .40 S&W is one of the most popular LE cartridges in the US. The .40 S&W has much better characteristics as a defensive round.

Yes, the 7.62x25 typically carries more energy.
But this round (7.62x25) is known for its extreme penetration (for a pistol caliber, surplus ammo can go through type 2 body armor). Due to the extreme penetration, this round tends to "ice pick"; or go clean through its target causing minimal tissue damage, so most of the energy of this round is wasted.Source(s): At one point I had a large investment of time put into 7.62x25

762x25 S&B 85 grain I have clocked right at 1800 fps; which is really moving. Tends to go through armor and everything like a hot knife through butter.

.40 had more power being heavier and larger, so it would be better for stopping a man, a 7.62x25 will penetrete more and will have more range.

I pulled these off Wikipedia.
Here is the 7.62x25mm:
85 gr JHP 1,230 ft/s 290 ft·lb
90 gr FMJ 1,340 ft/s 360 ft·lb
85 gr FMJ 1,650 ft/s 511 ft·lb
85 gr FMJ 1,720 ft/s 560 ft·lb
85 gr JHP 1,700 ft/s 527 ft·lb
And here is the 40 S&W:
135 gr Federal Premium JHP Reduced Recoil 1,190 ft/s 424 ft·lb
155 gr Warrior Arms JHP 1,235 ft/s 525 ft·lb
155 gr Guardian Gold JHP 1,205 ft/s 500 ft·lb
165 gr Remington Golden Saber 1,150 ft/s 485 ft·lb
180 gr Doubletap FMJ-FP 1,050 ft/s 441 ft·lb
So a smaller, lighter bullet moving faster ends up having more energy.Source(s): Wikipedia
