This was asked in the live chat for the last Triangle Tactical Q&A podcast, and I didn’t have time to get to it in the live show.
Anyways, I think it’s definitely worth it to get the cardboard targets. When I priced them out, they were ever so slightly more expensive than paper targets, however, I get several uses out of my cardvoard USPSA targets that I don’t suspect I’d be able to get out of the paper ones.
Also, I don’t think the paper targets would be as easy to paste as cardboard ones, so I think even if they’re more expensive, they’re worth it. Get cardboard, and generally MidwayUSA seems to have the best price for 100 shipped to my zip code.
