I had the same problem when I had one piece mounts on all my using rifles. They worked great and I loved them. But I wanted to use the Caldwell catcher that connects to a mount on the rail. With a one piece scope mount it was next to impossible. Just not enough room for everything.
Finally changed out all the one pieces for the Vortex high rings. Now I can mount a brass catcher on all my using rifles at the range or out in the fields.
When all you shoot is Lake City brass, you sure don't want to lose any more than you have to.
Also after having my lower back fused, the ground is kind of hard to get to these days.
Caldwell also puts out a brass catcher that mounts with a velcro strap around the hand guard. I never could get it tight enough to keep it from slipping down when the bag got a little weight to it. When I realized that it wasn't going to work I went to the rail mount.
