Actually it’s probably those without deep pockets. I know mine are really shallow. Still a great way to save cash. I really want to shoot thousands of rounds in any weapon I will be using, to build muscle memory. Be that a pistol or shotgun. With the price of ammo., being able to utilize a 22lr for a few thousand rounds has to save what, $500-$600. I haven’t done the math, but I guessing that’s pretty close. Probably even more. If the kit only costs $300, it’s a cheap way to build familiarity with the pistol.
