Never used a cartridge type bore slighter before. Works better than the type that slides into the end of the barrel. Feel confident about the results.

I used this to bore site my new rifle and scope. I could not get the scope to properly align and thought there was an issue with the scope. I took out my old bore sight and was able to correct it. The laser is crooked SMH
