In rifles this 100 grain #1560 Spitzer Boat Tail bullet with a heavy double-tapered jacket ensures adequate penetration with reliable expansion on medium game. It is the boat tail counterpart to the flatbase #1540 Pro-Hunter bullet but when ranges exceed 300 yards the #1560 bullet is the choice for best downrange performance. This bullet is exceptionally accurate and it may be used in 6mm cartridges such as the 243 Winchester 6mm Remington and magnums. It also is a very fine bullet for larger varmints at long ranges.
For handguns the 100 grain #1560 Spitzer Boat Tail bullet is too “hard” for use in the field on game because it will not expand adequately at the moderate velocities attainable from all cartridges except the largest wildcats. This bullet will perform to outstanding levels in long-range target or silhouette competition from barrels with standard twist rates.
