The Umarex SLA .50 Cal 388 grain hollow point is what you reach for when your big bore air rifle is doing real work in the field. These are solid lead ammo (that's what SLA stands for) sized to a true .510 diameter and built specifically for the Umarex Hammer and similar .50 caliber PCP hunting rigs. At 388 grains, this is the heavy end of the SLA lineup, and that extra mass is exactly what you want driving deep on larger game.
The hollow point profile is the star here. Soft lead construction means the nose opens up on impact for controlled expansion and strong energy transfer, which translates to fast, humane takedowns on hogs and other big game. Slugs like these carry a better ballistic coefficient than round balls or light hollow-skirt pellets, so you hold energy downrange and get flatter, more predictable flight when the wind picks up.
These seat cleanly in the Hammer's magazine and feed without fuss. Field reports from real range time back that up, with tight groups around a couple inches at 50 yards and respectable performance stretching out toward 100 yards even in breezy conditions. If your rifle likes heavier projectiles, this weight tends to reward a good scope and a little tuning to dial in your drop.
Big bore airgunning lives and dies by the ammo you feed it, and stepping up to a purpose-built solid lead slug over a lighter pellet is where accuracy and knockdown really come together. Each box holds twenty slugs, made in the USA, giving you a solid supply for sighting in and heading out. Pair them with a big bore rifle set up for slugs and you've got a combo ready for serious hunting.
These slugs are made for .50 caliber big bore PCP air rifles built to shoot slug ammunition, with the Umarex Hammer being the primary match. They're sized to a true .510 diameter for a proper fit. If your rifle is chambered for .50 cal slugs, these will feed and seat right.
The 388 grain is the heaviest in the SLA lineup, so it carries more mass and energy for deeper penetration on bigger game. The hollow point opens up on impact for controlled expansion and strong energy transfer. If you're after the most knockdown for larger animals, this is the one to grab.
Real-world testing shows tight groups around two inches at 50 yards, opening to roughly four to five inches out at 100 yards even in wind. The heavy slug flies stable and predictable when your rifle is tuned for it. Pairing them with a quality scope helps you get the most out of the accuracy.
Each box contains twenty Umarex SLA 388 grain hollow point slugs. That's a handy amount for sighting in and heading out for a hunt. The slugs are made in the USA for consistent quality.
