Anybody have any success using a moderator on a powerful spring rifle like the Beeman R1? I read an article written by Robert Beeman some years ago who said moderators had little affect dampening sound on magnum springers due to the very small amount of air that is used and exits the barrel when shooting a pellet. However, I am interested if anybody would like to share their direct experiences with moderators on magnum springers that shoot pellets at less than the speed of sound. If anyone has found that moderators work well on magnum Nitro Piston rifles that would be interesting to know as well as a comparison .... thanks !!! Almost forgot ... anybody have any success in dampening the sound of pellets hitting a steel pellet trap, I tried putting ballistic putty on the back side of a pellet trap which did help but not quite enough, any ideas you'd like to share?
