I have been shooting C size IDPA steel style for a while and enjoy it, but we thought we would try something new. I have seen these (but much bigger and nicer) used in competitions. I painted the raw metal with cold galvanizing and then painted the targets white with this fancy paint. I was surprised how quickly it arrived and how easy it was to put together. Seems well built and designed. It has two spring tension locations for heavy or light rounds. Any advice?
