Should check into making a grease board. You can photo results and still take them with you. Its reusable and doesn't require all the paper targets. We have one at the WSRC and it works good except when idiots shoot slugs at it.
After you fire your shotgun at the grease board you take a paint roller and roll over the pattern that was made on the board. You can then shoot at the board again and continue the above process. I have seen clubs use grease even Crisco and it works fine.
The grease board is a large stell plate with a center circle welded on. You have a bucket of grease and a paint roller on a long stick. After each shot you snap a photo for your data records and then roll the fresh grease over the steel plate. Its fresh and ready for next shot. I'm not sure of the type of grease or sizes as i did not design it. The grease appears grey in color. hopefully a more knowledgeable person will comment on it.--Matt
Robert, Dennis Devault has a design very simular to the ones above made with all 2 inch pvc tubing. You don't have to glue everything together if you don't want so it can be taken with you. It works with the paper rolls as well. I'm sure he would give you all the info if you ask. Break-em all. Jeff
Here's something simple that I made out of PVC pipe --- if you don't glue everything it's light, it's easy to take apart and you can carry in your trunk. Pre-cut the paper to the appropriate size and you're good to go.
I like Neil's design because you can put a roll of butcher paper and clamp it up at the top. Then you can rip it off and start all over again. With this design after the supports start getting ragged you just install new ones.
bryan, thats not butchers paper!!! Go to Home Depot or local lumber yard and get a roll of construction paper. Its made to protect the floors of homes under construction. Its a thick and tuff paper and a roll is like 100 ft. long and about 3 feet wide. Perfect for like 33 test patterns for like 10-13 dollars or so. 3 feet by 3 feet is perfect size. Break-em all. Jeff
