Pellet trap...just tape some magazines or newspapers together. If you know an electrician that can get this stuff in bulk it makes a great silent back stop.Cool M1 (or should I say 'cuell'?)
I think Leominster is running 100 yard offhand matches during the winter, but I shift into ski racing mode and wouldn't usually have the time to head up there. I'll squeeze in some time at my local club and pellet rifle basement practice if I can find my pellet trap. If not, guess that can be a Christmas present.
