This bullet frequently gives half minute-of-angle groups when loaded to near maximum loads in 270 caliber rifle cartridges. It is also an ideal selection for medium game at ranges up to 400 yards. This bullet features double taper jacket construction for good penetration and dependable expansion on medium game.
These rifle bullets were designed specifically for proper feeding in the 30 M1 Carbine. The 110 grain Roundnose #2100 is a soft point expanding bullet that expands reliably at carbine velocities. This bullet can be used in all 30 caliber cartridges (at reduced velocities) for small game.
In handguns of 30 caliber, these bullets are best suited for informal target shooting or varmints at close range.
In rifle cartridges, these bullets are highly recommended when good expansion and deep penetration in medium and heavy game are required at short to medium ranges. These bullets give pinpoint accuracy because of their short lengths for their weights. This short length for a given weight allows a rifle barrel to stabilize a considerably heavier roundnose bullet than would be possible with a Spitzer-pointed bullet of the same weight, which would be considerably longer. If the shots are fast and at short ranges or the game is big and dangerous, these are the bullets to choose. The 180 grain #2170 is suited to larger game but will perform well on larger whitetails.
In handguns, these bullets should be considered nonexpanding in game at normal handgun velocities. They may prove useful in situations where a heavy bullet is needed but twist rate is marginally slow, such as Handgun Silhouettes where momentum is more important than expansion. The shorter length for a given weight of each of these bullets, compared to longer Spitzer-shaped bullets of the same weights, may provide superior stability and accuracy in some handguns.
The #2170 was introduced in 1961.
Sierra offers a single flatnose bullet in this 45 caliber specifically for the 45-70 bore size. It may be used in rifles or handguns with a .458 inch bore, but it must not be used in handguns with .451 or .454 inch bore size.
Sierra introduced this bullet in 1973 - the 100th year of the 45-70 cartridge. Now, decades later, this old cartridge is still growing in popularity and justifiably so. Adequate for any game in North America and offered in several modern firearms, this old cartridge is just plain fun. The bullet is unique in that it expands well at modest 1873 Springfield velocities or at the more powerful full charge velocities that can be loaded in stronger action types, such as the Ruger No. 1 and No. 3 and Marlin lever actions. Accuracy is excellent, and it feeds reliably through all types of magazines and actions. It can be used in the 458 Winchester Magnum cartridge, but muzzle velocities should not exceed 2500 fps.
For handguns, this bullet was designed to expand reliably even at 1300 fps. It is a perfect match for the T/C Contenders and similar handguns chambered for the 45-70 cartridge. Dependable expansion and excellent accuracy make this Pro-Hunter bullet a good choice for most hunting situations.
