If it is avaliable. I used to take a regular cardbord box anf then fill it with shipping shrink wrap. Even at 10 yards it would not pass thru. Not waterproof but all I had to do was replace the box when it got wore out.
I guess it isn't exactly home-made, but years ago I called a company that makes shipping crates and packaging materials for where I worked. I noticed the containers that they made for us had that same kind of plastic like foam in locations that is in targets you buy. So I had them make me a 4'x4' backstop out of it for my backyard, and is three layers of I guess 1 and a half inch(?) foam glued together. That was like ten plus years ago and I still have it, but now starting to show it's age some, ha!
My friend goes to a feed store and bought bales of hay that works good too.
I like to use pages from coloring books, and magazines tacked to it as spots to shoot at.
We have a place local that sells accoustic tiles for drop ceilings. My friends and I went by and got a 4 x4 styrofoam block that they make the tiles from. They have been shot for years and are doing fine.
I took a cardboard box and stuffed it full with old phone books and then filled in the gaps with tightly packed plastic shopping bags. Works like a charm! I also stuff old feed sacks with other old feed sacks and plastic bags, just be sure to get them packed in super tight!
I've made a target with a bunch of strips of cardboard sinched between 2 peices of all thread with a 2x4 on top and bottom. The strips were about 4 feet long by 10 inches wide. Stack the strips on top of eachother and put a 2x4 piece of wood on each side to keep the nuts from pulling through. The hardest part is drilling 2 holes through each piece of cardboard. After getting enough strips stacked on top of each other sinch it down tight between the wood.After that I made a stand out of some old c channel I had laying around.
I left it out in the rain a while back and it didn't last too much longer than that.
The easiest way to make a target is to take packing plastic and stuff it inside a burlap sack.
My bow shoots pretty fast so I have a store bought target now to keep from losing any arrows.
Accuracy. What an incredible way to give yourself a true advantage.
Go to your club and get a bunch of guys together - and put a target out there at 250 meters. Break out the deer rifles and see who can shoot a decent group, even off of the bench, at this distance. I think you will be shocked at how few can do it.
So - with that in mind, I recently set out to try to develop a semi-custom rifle that I could afford and that would shoot - repeatedly - at MOA.
I started with a platform that I love...
