Your question about how long an individual Target Box will last, is a good one. Depends on two things: What caliber weapon you shoot, and where you typically strike the Inter-Targets. My favorite target shooting weapons are .357 (pictured on the website), and the 9MM. With those calibers I don't normally lose more than one or two of the ten Inter-Targets in a box (50) of ammo. With something like a .22LR I'm thinking you can shoot a long time, for a lot of days before the Target Box is completely wasted.
To be honest Dave, I would order a few extra targets because shipping has gotten so expensive. I think you'd rather let me pay the extra shipping than order more in a month or two, because they beat the heck out of boring paper target shooting .
I'm getting a lot of orders, but I'll get your order out A.S.A.P. when I receive your snail-mail-check. Thanks again,
