I used 5/8" plywood, can usally pull them with a rubber grip arrow puller. This one is 5.5 feet wide and 6 feet high. Thats a 24" x 27" bag hanging in front of this 50 yd target. Only one arrow has ever missed that back stop, my 11 year old grandson has one down in there. It's #8 on my 14 target field round, so 32 arrows shot to get to here, lost his 3rd shot down there.
