Its a little loose in the chamber so it's not overly accurate.

In the past, I have mostly used the bore sighters that fit in the end of the barrel and shine a laser-like beam from there. Precise fit is a bit difficult. This type - which fits in the cylinder of my revolvers - Is MUCH easier to use, and seems more accurate - and therefor more precise. Used it recently to check the zero on four .44 mag revolvers, and also on one in .480 Ruger, which fit close enough to "do the job".
I'm satisfied with this equipment!

It solved my sighting issue with my fixed sight Ruger Vaquero, I know my front blade orientation. It also let me know my rear sight on my 10.5" Super Blackhawk was off. Thank you!
