Buffalo Bore pushes more power into the .357 Magnum with its Heavy load (load no. 19D20), driving a 125-grain jacketed hollow point at increased velocity for revolver owners who want maximum performance from the caliber. Buffalo Bore built this load to run safely in any all-steel .357 revolver, including compact J-frame-sized guns, while cautioning against use in super-light alloy-frame revolvers that cannot handle the added recoil and pressure over time. The jacketed hollow point is tuned to expand reliably at the higher velocity this load generates, converting extra speed into a wider wound channel. For revolver owners shopping handgun ammunition who want genuine full-power .357 performance, this Heavy load delivers it.
