Wax when heated (remember this july) tends to melt and then then don't eject/feed well. If keep in a cool dry place (not the back of the truck) it works better. It is dirty and not so accurate. Given the choice I would go federal or winchester.
I have seen one case seperation at the range with the golden bullet but it might have fired out of battery. never saw a round of anything else in rimfire seperate a case.
In the 525 round box of Golden Bullets I have right now, many of the bullets are loose enough in the casings that you can spin them around, or they wobble to and fro. I'm getting more duds than I get out of other brands, and some of the bullets are slightly deformed.
I'm sticking with CCI Blazer and Federal AutoMatch bulkpacks from now on.
