Any of you guys that reload for long range. Use this tool? Is it worth it? Whats your opinion, likes or dislikes. Thank in advance.......Hilltop

I have some friends that use that one and I think it's as good as any.  I have the one from NECO and it works well for me. 

It's one of those tools I have to check my work, every so often.  I can't say that I use it a whole lot, but, like a few other tools I have, I wouldn't want to be without it either.

My reloading coach introduced me to this tool. We've saw big improvements in accuracy once we were able measure runout and make adjustments using the hornady tool. We aim for 0.001 - 0.002 of runout. This tool allows you to correct for runout where other tools only allow you to measure.
