RCBS Bullet Puller o-ring
 

Does anyone know what size the O-ring is on an RCBS Green Plastic bullet puller?
My o-ring collection does not have one that will fit
Is is Metric 20 x 1?

colony,

Why not give RCBS a call; they will probably send you one or two for free?

Actually, you don't need an o ring. You will discover that you can remove the collet and replace it with the appropriate shellholder for the cartridge you wish to pull the bullet from. IME, it's just as fast if not faster, and as far as I can tell, doesn't harm the shellholders - I've been using shellholders instead of the collet for years.

Thanks Jack.
 

That suggestion makes you a lot smarter than me.
It worked great. In fact it is better than the three piece and oring.

Well duh...a good one Jack..My puller has a metal spring...Old...is not always better..but smarter is thanks for sharing your smarter

Thanks guys, but. . . I believe I stole that idea from Rocky, a long time back. :D
