I cleaned and lubed my RCBS JR3 press a few days ago, which I bought in 1973.
There was no slack or wear anywhere, which was nice.
The only problem that it had was the top of the ram where the shell holder fits in.
Many years ago, I had stupidly used the press for some forgotten makeshift project without a shell holder in place, and had dented the top of the ram.
It was my fault and not the press.
It still worked fine but it has always annoyed me, and all the more so with it now cleaned up and lubed.
Anyway, I contacted RCBS by e-mail and they are sending me a new ram and shell holder retainer clip at no charge.
Not bad service by a company for a 44 year old press.
And it will be ready to go for another 40 years.
I'll be dead long before then, but the new owner will be happy with it.
