What They Are, What They Aren't
The next step was to develop big-game cartridges based on the shortfat design, and this was done in the late 1990s. And so we now have the Lazzeroni line, which offers shortfats in .243 through .416. Winchester has shortfats in .270, 7mm, and .30; and Remington makes them in 7mm and .30. All shortfats are loaded to high pressures (around 65,000 psi) and all of them will equal, or slightly better, the velocities of standard magnums such as the 7mm Remington and .300 Winchester-and they do it with about 10 percent less powder, which means slightly less recoil.
