The Thompson Center Maxi-Ball 370gr pre-lubed muzzleloader bullet combines reliable performance with the convenience of factory lubrication, making it a practical choice for hunters shooting traditional and modern in-line muzzleloaders. These .50-caliber projectiles arrive pre-lubed with Natural Lube 1000 Plus Bore Butter, eliminating the routine chore of swabbing your bore between shots in the field—a real advantage when you're focused on a stalk or waiting for the right moment at a stand.
Built for deer and elk hunting, the 370-grain Maxi-Ball design delivers the expansion and knockdown energy needed for effective large-game harvests. Because this bullet design typically works well across a range of barrel twist rates, it's adaptable to many traditional muzzleloader setups and modern rifles alike. If your state imposes strict bullet restrictions during muzzleloader season—common in states like Oregon and Idaho—the Maxi-Ball's profile often meets those regulations where hollow-point and jacketed ammunition may be prohibited.
Each box contains 20 bullets, giving you a practical quantity for hunting trips, practice sessions, or range testing. The pre-lubed construction saves preparation time and keeps your shooting simple: load, aim, and fire without the back-and-forth wiping that traditional unlubed bullets demand.
