The new TSMZ line was made to extend the range of the common inline muzzleloader, offer a non-lead projectile that is more consistent, and provide the terminal ballistics that DRT is known for. Our powdered core has given the bullet an unprecedented stability and will shoot less than a minute of angle at 100 and 200 yards out of a quality rifle.  We used a 115gr of Blackhorn 209 with CCI 209 shotshell primers and a Thompson Center Triumph to test this bullet for accuracy.  We also used 150 Gr (3 pellets) of White Hots in a TC Encore Pro Hunter. The TSMZ is a powdered core, just like our other projectiles, and is incredibly devastating.  As you can see from the Permagel block, the bullet travels into the target and then expands. The bullet will pass through bone and parts of the bullet core remain in tact continuing to move through the animal, which makes it perfect for hunting – causing massive internal damage.  This truly is an accurate and deadly bullet, unlike any other available.   Contact Nathan@drtammo.com
