Nope.
Apply force to press handle as cases enter dies. Ram shifts in bore and deflects toward front of press.
Not difficult to understand.
No, not at all hard to understand.
Also not hard to understand that shell holders/shell plates are slotted, brass moves freely for a pretty large distance (machine tool speaking) allowing the brass to align with the fixed die.
I'm pretty sure that wasn't the intended purpose of the lotted shell holder, ease of swapping one case for another was, but the end result is the brass can move to make small corrections when entering the die.
Why measure it? Because too many cases (pistol or rifle) were clipping die mouths and I wanted to know why.
That's an easy one!
YOU didn't correct the index of the shell plate to align the brass under the die well enough to get it started,
OR,
YOU didn't adjust the case feed shuttle to get the case under the die.
Not a fault of ram or machine! Operator error!
As for cause of ram/frame wear, probably lack of lubrication, about the only way to wear a ram/frame out.
My 650 (properly lubricated) went over a million before the frame needed bushed, the ram was fine & reused, aluminum not being the best bearing material & needing frequent & proper lubrication.
The 1050 went about 1.5 million before it needed rebuilt & a new ram.
It's gone another 2.5 million with a roller bearing & new factory ram with little sign of wear.
(Roller bearing rock!)
So again, I have to call BS and blame it on operator error.
You know, like from the guy that couldn't get the machine adjusted in the first place or doesn't know cast iron deflects...
