There is a reason for this; these bullets expand well and usually penetrate more than a foot in ordnance gelatin. They are also establishing a good track record when it comes to defeating intermediate barriers. DoubleTap is now offering a 125-grain Barnes TAC-XP load for the .40 S&W, and its blistering velocity will drive this bullet deep and help it to create a decent sized wound cavity. If you like high velocity and a bullet that will stand up to the speed, this might be your load.
| Load | MV (fps) | PEN (inches) | EXP (inches) | RW (grain) |
| .40 S&W DoubleTap 125-grain TAC-XP | 1,419 | 17.25 | .60 | 125 |
