TRUMARK’S 5/16" STEEL BALL AMMO has been carefully selected.
Ammo that is 1/4” in size is too light and tends to “tear up” wrist-braced slingshot bands
that need more weight in the pouch when shot.
Steel ammo that is larger than 3/8” is too heavy and is unsafe if used improperly.
Trumark’s ammo is the ideal size for shooting in wrist-braced slingshots.
225 Yd. Range when shot with Trumark wrist-braced model slingshots.

In 1954 Trumark introduced the first slingshot ammo that is really fun to shoot
No. SA50 Tracer® Brand Ammo!
White marbles reflect light so that the eye can "trace" the ammo's path like a tracer bullet.
Seeing the ammo clearly as it heads toward the target, makes it easier to become an expert.
The bright white color also makes Tracers easy to find so they can be shot many times.
The Tracer's large 1/2" size is easy to grip so that the powerbands can be pulled
smoothly with less hand strain. Excellent for target practice!
