.366 | 300gr | Swift A-Frame
by Swift
The Swift A-Frame is a legendary bonded and partitioned hunting bullet designed for the deepest penetration on the world's largest and most dangerous game. Its unique construction features a front lead core bonded to a heavy copper jacket, backed by an internal partition and rear lead core for maximum weight retention exceeding 95%. This dual-core design ensures controlled expansion in the front while the rear drives through for maximum penetration. The A-Frame is the bullet of choice for Cape buffalo, elephant, and large bears where failure is not an option. Its semi-spitzer profile feeds reliably in all action types.
