It reminds me of folks who spend $60+ for a brass catcher.
I figure that my most expensive cases or 9x21 and .32-20, where I bought StarLine virgin cases years ago and replacement cases are $0.15. So, I would have to lose about 400 cases to pay for the unit. I lose about 1-2 9x21 cases every trip (don't lose any .32-20, as they are shot in a revolver) and I shoot those about 6 times a year, so I lose maybe 10 cases a year, or 40 years to pay for a brass catcher. At 66 years old, I could only hope to have 30 years left.
You have to stop once in while and think about what you are doing and if it really makes sense.
However, when I take someone to the range, I tell them that every case we fire is equal to a dime for me, so I would really appreciate it if they helped pick up cases after we're done.
I have a pretty expensive catcher on my AR(S) the amount of time, work effort I put into preping brass (which I dislike) I am not losing mine!!
Yes it is expensive but is very well made it is heavy duty not like those Velcro junk ones. You can buy extra rail mounts to put on other rifles (Those are from the company and expensive.
Caldwell seems to have a copy of it now but have not seen it yet.
