For rifles in 30 caliber, this bullet was designed for medium- to long-range hunting with cartridges having medium to large case capacities for powder. These bullets often display match grade accuracy from accurate hunting rifles. The famous Sierra Spitzer Boat Tail shape assures flat trajectory, excellent resistance to crosswinds and vertical winds, and maximum energy delivery to the target. Good penetration and expansion are characteristic of these bullets even at the reduced impact velocities at long range. With the weight range available, at least one of these bullets will prove ideal for almost any 30 caliber cartridge. The 150 grain #2125 bullet is best suited to medium game at all velocity levels.
In handguns chambering 30 caliber cartridges, prior to the introduction of the Remington Model XP-100 (and similar handgun designs) utilizing larger rifle cartridges, the usefulness of these bullets was limited. Now, these bullets have a very definite niche as superbly accurate hunting bullets. Previously considered “too hard” for expansion, they perform well at the 2500 fps muzzle velocities achievable in the 308 Winchester and larger cartridges. Ease of loading and precise concentricity contributes to their excellent accuracy. Sierra’s Spitzer Boat Tail design assures flat trajectory and high energy delivery downrange with low sensitivity to crosswinds and vertical winds. These bullets are suitable for varmints through large game at all ranges a prudent handgunner would normally attempt.
For rifles, this 150 grain #2115 Full Metal Jacket Boat Tail bullet is designed for semi-automatic types, and it functions flawlessly in the M14/M1A, M1 Garand and similar rifles. The cannelure is located to provide an overall length suitable for both the 308/7.62 NATO and the 30-06 cartridges. This 150 grain FMJBT bullet also is a good bullet at medium and low velocity for hunting game with valuable pelts to be preserved.
In handguns, this 150 grain #2115 FMJBT bullet is ideally suited to the hunter who requires a non-deforming bullet to minimize pelt damage. Velocity should be kept low, and ranges must be correspondingly short to minimize damage to the pelt.
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.
