The pellets were actually "stacking" behind the paper from using the same 5 bull ten meter target.
Well, since my pellet energy at 50 yards will be only half of the 15 FPE at the muzzle, I'll go ahead and use the half-sheet of 3/4" plywood to stop the lead, with a piece of carpet tacked on to help deaden the impact sound.I want to thank all the contributors with their original ideas for backstops.HAL the ELDER (Union artillery battery at our annual Civil War Reenactment at Calico Ghost Town in the High Desert)
NO BRICKS UP HERE...Our High Desert building materials stores (Home Depot, Lowe's), do not sell duct seal in BRICKS.They sell it in 64-oz TUBS, at $11.95 per tub.That's all.....HAL
That looks plenty tough Bryan. yeah, I bet it sounds like a loudspeaker. Can you sandwich an inch or so of newpaper between some cardboard box material, and make a cheap disposable sound baffling backing board? It'll close up the front, give an airgap, and muffle your metal deflecter. I use wineboxes and newpapers, and I need an enclosure like yours for a weatherproof enclosure. I could use half the paper with your design!
For mine, I'll tell you... I'm going a layered 3 door, with (2) hinged sides and the Top hinged door outermost. Open it up and rest the top on it, and it gives me 3 sides with a wide open front. The winebox/paper fills the opening inside. I think you get the idea.
You could also hang a piece of carpet over the front of it. It would muffle the noise, keep out rain and even if you shoot through it, the metal behind would keep things safe.The backing on the 2'x2' carpet squares is usually rubber too, making it more waterproof.
