Mystery solved.



Log in to see fewer ads
For months I have been trying to locate the source of a .127 ball bearing that appeared on my work bench. For any of you that have taken something apart and re-assembled only to find parts left over, you know the feeling I have been having. During that period of time I had worked on a bunch of SAI NM rear sights with the bearings and a few Savage bolt rifles that I took apart the bolts and put them back together. Being sure this freaking bearing came from one of those jobs, I went back over them all to no avail.
By chance today while loading a few hundred Berger 150 fb bullets I found a duplicate of the mystery bearing in the bottom of the container I dump bullets into for loading. Source turned out to be from one of the 100 rnd Bullet boxes from Berger. I have no idea how they might have found their way into them, but they were sealed when I opened them and dumped into the container which I had just cleaned and dusted this morning so I know it wasn't there earlier. Whatta Hobby!

That's the accuracy bearing! You know how packages of beef jerky have a little bag of silica gel inside to keep the jerky fresh until eaten? It's like that, but for bullets- to help them keep their factory accuracy until it's been "locked in" by the process of loading the bullet into a case.



Glad you tracked down the source. That would drive me, and I suspect most people, absolutely crazy until I figured it out. Hopefully something essential at Berger isn't leaking the guts of one of its bearings...

I suspect they are tumbled in them, and one made it thru the screening process?

I wonder if it's from a ball mill used to polish bullets just before packaging.

Had a PM on another forum with a very good possible explanation that brought out a good belly laugh. " Judging by the size it could be a snowflake ball ". And all this time I thought snowflakes were balless bags of hot air.

save it!!!

It will fit under the tang safety switch on any Mossberg 500 shotgun. I just replaced 2 of them. It rides on top of the small spring as part of the detent system.
