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

In rifles, this 100 grain Spitzer bullet #1540 has a heavy, double-tapered jacket to ensure adequate penetration with reliable expansion on medium game. This bullet may be the correct choice for hunting large varmints as well as deer or antelope. It also may be the bullet of choice in some rifle's because its flat base construction enhances accuracy in that particular rifle.

In handguns, the 100 grain #1540 Spitzer bullet is too "hard" for use on field game due to the moderate velocities from all but the largest wildcat cartridges. However, this bullet will deliver to outstanding accuracy in long-range target competition and high momentum downrange for silhouette competition from handgun barrels with standard twist rates.

The #1540 was introduced in 1956.

Wonderful bullet! Grouping at dime diameter @ 100 yds. w/ a 1:10 twist. An area for improvement is length consistency. Overall, wonderful bullet. I'll continue using them.

Tested on a 5x5 muley at 50 yards when my fiance touched the trigger. Bullet entered low in the chest at an up hill almost full frontal shot. I've seen other bullets lose at 50 and under, resulting in under penetration and this buck made it all of 2 surprised jumps before crumpling, hydro static shock left 1/2 of a lung and the bullet nicked the heart exiting midway back on the far ribs and from 100 yds we watched a bit of bone or jacket exit the far ham. This bullet is tough!!!!! Mv out of 20" youth was close to 2974! Next time we'll see if these (as we've dubbed them so as not to confuse my friends with my varmint loads) elk hammers work as good out to 300 yds or so where we were splodin pumpkins with em.

This bullet has repeatedly proved to be an outstanding choice on mule deer and antelope. Absolutely excellent accuracy (sub-1/2" at 100 yards) out of a totally stock .243 Win Tikka T3 Lite Stainless at 100 yards, and incredibly little meat damage even on close range shots. Buy some: you won't regret it.
