Thompson Center MaxiBall PreLubed Features The Thompson Center Arms MaxiBall is shaped to load easily down a muzzleloader bore while still delivering consistent accuracy at hunting ranges. Its lead semi wadcutter style profile is engineered for maximum expansion on deer and elk size game giving hunters confidence in a quick humane harvest. Because the bullet is pre lubed with Natural Lube 1000 Plus Bore Butter shooters can fire multiple shots without needing to swab the bore between loads a real advantage during a hunt when a fast follow up shot may be needed. This pre lubrication also helps protect the bore from fouling buildup over a day at the range. At 370 grains in .50 caliber the MaxiBall is sized to meet the bullet restrictions some states impose during muzzleloader season making it a practical choice where sabot or saboted bullets are restricted. The bullet performs well out of both fast twist modern inline muzzleloaders and slower twist traditional sidelock barrels giving it broad compatibility across muzzleloader platforms. Each box holds 20 bullets giving hunters enough projectiles to practice and still head into the field with plenty on hand. These MaxiBall bullets are for sale at GrabAGun for traditional muzzleloader hunters loading their own charges.
