PPH, I like your bench, looks like it would work very well. I also like the rifle, looks great. But I do wish the rag wasn't in front of the rest. What I can see of it it looks so simple to build one from some scrap lumber I have around here. Appears it clamps the rifle both at the forearm and the buttstock.
Sproulman, I would also like to have a perment shooting bench. Problem is I only have a place 25 yards I can shoot at home. I do have the use of the property next door where I can get about 125 to 150 yards before it starts running up a hill. So I can't have any thing perment there. I also wanted a bench at the cabin. One thing I have learned at the cabin is leave nothing out side. Includeing home made wooden gates and other triva stuff, for some reason they tend to walk off.
I had a fish cleaning table I had made and it had a old cast iron sink at one end, I picked out of a ditch one time. I still have the sink but the table just up and dumped the sink on the ground and ran off with the plastic barrel the sink drained into. Our cabin is so hidden there isn't even electric there. Hidden that is except for the drive/trail to it.
I also like the idea of setting it up on the edge of a cranberry marsh and pot shoting yotes as they cross.
