Description
The HEVI-18 TSS turkey load steps up the 20 gauge game with ultra-dense tungsten pellets that hit way harder than what most people expect from a sub-gauge shotgun. At 18 grams per cubic centimeter, this is the densest tungsten formula HEVI-Shot makes, giving you the kind of downrange energy and pattern density that lets a 20 gauge do things previously reserved for 12 gauges.
What Makes HEVI-18 Different From Other TSS Loads
The 1-1/2 ounce payload of number 9 shot packs incredible pellet count without needing a heavier gun or dealing with excessive recoil. Because tungsten is 48 percent denser than lead, each of these small pellets carries serious stopping power. Real-world testing shows the number 9s will put over 200 pellets in a 10-inch circle at 40 yards through a factory full choke, which is the kind of pattern density that leaves no room for error and makes sure you get the clean kill every time.
The Spherical Buffer System
The shell design includes a friction-reducing spherical buffer that keeps pellets from deforming during the shot. This means your patterns stay tight and consistent, round after round. The crimp-seal resin holds everything in place and resists damage, so you can carry these shells in the field without worrying about them coming apart. The whole package moves at 1250 feet per second, which is fast enough to extend your effective range without feeling like you're shooting a magnum load.
These 3-inch shells come packed 5 per box for practical field use. If you're hunting with a 20 gauge and want the performance of a heavier gauge without the weight and recoil, HEVI-18 is the real deal.

Frequently Asked Questions
How do these HEVI-18 shells compare to regular lead turkey loads?
The ultra-dense tungsten pellets carry more energy downrange, which lets you effectively drop three shot sizes smaller than lead and still have more stopping power. A number 9 TSS pellet hits like a much larger lead shot, so you get higher pellet counts and tighter patterns without needing a bigger gun or magnum loads. Real testing shows these shells put over 200 pellets in a 10-inch circle at 40 yards.
Will a HEVI-18 shell work through my standard turkey choke?
Yes, these shells are designed to work through factory full chokes and turkey-specific chokes. The friction-reducing buffer system helps the pellets flow smoothly without the excessive pressure you might get with some other TSS loads. That said, it's always good to pattern your specific gun and choke combination before hunting season to see exactly what you're working with.
Is the number 9 shot size actually suitable for turkey hunting?
Absolutely. In traditional lead loads, number 9 would be too small, but because these TSS pellets are so dense and hard, a single number 9 tungsten pellet hits significantly harder than larger lead shot. The sheer pellet count combined with the density and energy retention makes these loads deadly on turkeys from 25 to 50-plus yards depending on your setup and skill level.
How does the spherical buffer help with pattern quality?
The spherical buffer reduces friction between pellets as they travel down the barrel, which prevents deforming and keeps shot from deviating off course. This means your patterns stay consistent and tight. The crimp-seal resin also holds the buffer in place even under field conditions, so you get reliable performance shell after shell.
