Our clay ammo bands are made-to-order by our very own Wes Mitchell. We use 0.45mm latex (your choice) tapered 18-10mm with an active length of 240mm (9.45”). These bands are meant to shoot 3/8” clay ammo; you should trim them to your preferred active length before using them. We recommend using an elongation factor of 1:5-5.5 (500-550%), which will enhance band performance without causing premature failure. For someone with a 30” draw length, that would be 30/5  (6”) or 30/5.5 (5.45”). They would simply trim their band set to ~5.5” or 6” with a sharp pair of scissors or rotary cutter, ensuring that both sides of the band are even. We use 56mm microfiber pouches on these band sets, but the color choice is yours!
