if this thread belongs else where just let me know where it gets moved to.

I would like to build a big target.  something on the order of 4' wide and maybe 4'-6' tall.  I've seen a few photos of targets made out of 2"x4"(6") that have allthread on the sides to compress whatever material is getting sandwiched.  What is that material??? cardboard???  I wouldn't think that foam would last too long.  

ALso can a target like this withstand alot of broadheads??

The best thing we found was used carpet. You can get scraps for free at  carpet dealers. cut into a 2 ft x 4 ft pieces---stack up and then compress with a bander. Lasts a long time. We have also used cardboard, but carpet lasts longer and when it gets shot out, just replace that section.

carpet. My local club uses it exclusively. Cut squares the size you want. Like 3 foot by 18 inches. Stack 'em 4 foot tall amd compress them with 2x4's and all thread. When the centers start getting ratty, unscrew and rearrange the carpet. turn them around, stack the ratty ones on the ends. Know what I mean?
Just go to your local carpet store and tell them what your looking for. They should be happy to help as it saves them a trip to the dump. (including the costs). He might even be courious enough to come to the range.
We found a hotel that was recarpeting and got enough to make 10 bales. Good excuse for a pizza party.   :D      :D      :D

cool, thanks for the info

The carpet target well eat broadheads.

Celo Tex. Get it from Home Depot, Lowes etc. used as house siding when building a house. Comes in 4'x8' sheets. Last on I had lasted 14 years or so. Cost about $90 total.

Not to hijack, but how does carpet do vs. broadheads and woodies? Does it tear them apart?

I used cardboard for my target.   It can be picked up free if you want to put the time in to collect it, or you can order it from someplace like ULINE.  Stacked on a frame with the 'ribs' or corregations facing the shooter, threaded rods on the side to compress it, it works great.   I have had mine for about a month, shot it almost daily and can hardly tell it has been shot at.   Like other stacked materials, it can be shuffled around if one area starts showing wear, or if you want to shoot broadheads for awhile.   I ordered my cardboard and have @ $120 in my target--30" wide, 32" tall, 12" thick, wheels on the bottom to roll it around on. Better than any block, bag or cube I have ever used.   Including the ones with "self-healing" foam(LOL).

Sipsey, did you have to band those sheets? Or is their weight enough to do the job?
