I just bought one of these things: http://www.rightnowrange.com/

It set up real easy, and I was going to take it to the range this morning to try it out, but, for the first time in 7 weeks, IT'S RAINING!

These things cost 30 bucks a pop, so they're kinda pricey, but since I can use it over and over again, I thought it would be worth a try. I'll give a report once I've actually shot some holes in it!

I took the Right Now Range out to the range, set it up, and put some rounds on it. It's basically a good system, but here in Central Texas, the winds are strong and pretty steady. The Range did a bit of "rocking and rolling" while I was shooting, even in a 10mph wind. I added some 2 X 4 "feet" to it, and it helped considerably. Don't yet know how it's going to handle a wind from directly behind or directly into it. May need outriggers to handle that wind scenario, since the footprint is rather narrow, front to rear.

Not raining here and we have berms every 100 yards to 700 yards

Interesting concept
