a squirt gun....haha.
I use to use the leupy's, then found the talley's, both the lock/screw on, on my .340wby, then got the lightweights on the .243win, both were very nice, kinda how I'd make'em if I made rings, which in gunsmithing is nice to see compare to loose/sloppy how most things are...
dnz might be nice, I really don't know, perhaps I'll check'em out on the next rifle, but I'm perfectly content with the talley's, so I really don't see a reason to change.
I've noticed quite a few custom's rifle makers use Talley's
I think unless I really had a big boomer those lightweights are the way I'd go!
