Thompson Center’s Original Maxi-Ball has been used extensively by target shooters and hunters for almost 20 years. Its reputation as an exceptionally accurate bullet is unequalled. The wide lubricating grooves hold generous amounts of lubricant, the key to easy and consistent loading. Maxi-Balls are lubricated with Natural Lube 1000+ Bore Butter eliminating the need to wipe the bore or clean between repeated shots. The Maxi-Ball is the preferred bullet of experienced hunters who look for the penetration needed for large game like elk, moose or bear. Mfg: Thompson Center
