No factual reason at all. Other than “Why not?”M-61 you say a press means nothing to your loaded ammo so tell me then why do you put an "O" ring under your die.
The brass is going in the die and centers itself if I haven’t pushed it all the way back in the shell holder. The ‘O’ merely lets the die float a bit. It is something I’ve always done, probably not needed at all. For the price of an ‘O’ ring, I’m in!
As I stated above the press has nothing to do with accurate ammo.
Do I think the ‘O’ is a cheap and maybe helpful? Yup. Am I recommending anything or giving instructions? Nope.
As I’ve said in many of my posts I’m not giving advice or instructions to anyone. Everything I write is merely my experience with my reloading or rifles. Not anyone else’s. Eventually I’ll not post anything.
It’s easier.
