TMX (Tungsten/Iron) This is a high velocity non-toxic alternative. The pellet is manufactured using a Tungsten and Iron formula which has two distinct advantages, one it is approximately 20% cheaper to manufacture than Tungsten Matrix, secondly it produces tighter patterns at higher velocities. Expect patterns up to 90% at 40 yds with a velocity of 1400 feet per second.
