6mm .243 Caliber (.243) 100 gr. SBT

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.

Preaty good round. I have shot a number of Fallow deer with them using ADI 2209 @ 38.5G. Usually they drop on the spot. The bullet usually passes through. I have only recovered one and it lost about 40 grains.

I have used these in my Winchester 670A for many years for deer and even a few elk. They perform flawlessly, as all Sierra products have for me.

Without a doubt, the best bullet I've used in 243Win on game! @ higher velocities, it'll bring down anything in Oz, with a well placed shot. Mushrooming's an issue @ longer ranges, but use a Magnum if you want to "project some force"!

Henry C of Downsville, Louisiana October 13, 2013
I have hunted with the Sierra 6 mm, 100 grain SBT bullet for many yeas in Arkansas, Louisiana and Texas. The bullet shoots excellent groups and is more than adequate for deer. Most memorable hunt was in Jeff Davis Co, Texas huning mule deer in the mountains of west texas above 5000 feet elevation. A single shot on a 10-point muley, through the lungs, resulted in the deer piling up after running the typical 50 yards. Load was for 6-284 Win. with a muzzle velocity of around 3300 f/s. Henry
