Photos: OATH Ammo Unveils Powerful New Expanding Slugs


There were plenty of surprises from SHOT Show this year, but perhaps one of the most unexpected was the reveal of a new line of expanding and fragmenting slugs from OATH Ammo. The segmented slugs look like something out of science fiction, and OATH boldly states that they’ve solved the age-old problem of over-penetration from traditional 12 gauge slugs.

According to, OATH is offering a 1.25-ounce all-copper expanding slug and a 2.25-ounce all-brass frangible slug. Both include a copper or aluminum die visible in the center of the projectile. The all-copper slug is estimated to have a velocity of 1,600 fps and can expand up to 2.5 inches on impact—about the size of a fist. The heavier fragmenting slug is a bit slower at 1,200 fps, but will break up into a half-dozen 158-grain shards upon impact. Both of the projectiles seem to have been designed with power in mind and OATH states that the slugs can be used for both self-defense and stopping large, dangerous game.

What do you think? Is this something you would like to try out? If you said yes, you won’t be the only one. The new slugs apparently generated so much attention, it temporarily crashed OATH Ammo’s website.

“Due to the overwhelming demand on the two 12 gauge articles and ShotShow reveal our website could not handle the bandwidth,” OATH wrote on Facebook. “We are currently working on resolving the issue. We are sorry for the inconvenience.”

As of Tuesday, the website is back up but only in a limited capacity. The company expects to start selling the new slugs later this month or early in February.
