Took a trip over to Spinjag's webpage. They've been busy. They do have jags specific to some Parker bullets. They did not allow just the tips to interchange, no doubt hoping for an occasional $20 sale versus multiple $7's.

That alignment tool made specifically for Barnes MZ bullets is not like the spin jag. It's name is very misleading actually. It is solely designed to fit the olgive and nose contour of that specific bullet. It does NOT have a bore alignment ring that is 50 caliber specific like the spin jag does. It's simply a fitted end loader for a specific bullet. That in itself MAY allow for better alignment but not as well as a spin jag with a bore fitting ring to keep the jag straight would be.

Your assumption is the Barnes is the same size as the cut away part of the Spinjag. It's not. It's the same size as the larger part of the Spinjag.
They both fit the bore tight. If anything the Barnes might fit tighter.

Wrong. I've owned both of those jags. They both fit the bore tight. The Spinjag is cut smaller in the front is to keep the jag from pinching sabots. The Barnes doesn't have that, but the whole jag is the same size.

Pete, you obviously didn't pay attention to either jag then. The larger part of the spin jag isn't what rides the bore, it's the alignment ring at the upper part of the jag that rides the bore and keeps it centered. I also have both and can tell you without a doubt that the barnes jag does NOT ride the bore. It's not sloppy and there isn't a LOT of play (couldn't use it for a cleaning jag) but there is play and it doesn't ride the lands.
