The Double Tap Controlled Expansion .45 Colt +P 250-grain Semi-Jacketed Hollow Point (Double Tap part no. 45P250CE20) pushes the classic .45 Colt revolver cartridge to genuinely modern performance levels. At +P pressure, Double Tap rates this load at 1,375 fps, a significant step up from the mild velocities .45 Colt originally ran at in the 1870s. The semi-jacketed hollow point is built to expand reliably on impact while the exposed base helps retain penetration depth. This is a serious defensive and hunting load for strong-frame revolvers rated for +P .45 Colt pressure, not a load meant for vintage or lightly built revolvers.
