One of my MECs, a Grabber, has been on 4 benches since 1975 with the original collett and it's still cranking out shells. It was my only loader for many years and still handles one of my two favorite loads. No way to estimate how many rounds have gone through it.....breakemall.....Bob Dodd
I have had my 9000G for 8 years with one heck of a lot of shells run through it. I load for my son and myself and we shoot trap singles and doubles and skeet and I have done NOTHING to my 9000G except one minor adjustment to seat my primers a little deeper and that was earlier this spring - no problem since.

I have a Sizemaster 77, Grabber and 9000G. I loaded on the Sizemaster for about 10 years and probably loaded 30,000 - 40,000 shells on it without lubricating the collet (shame on me). It finally broke when one of the fingers broke off. I replaced the collet and bought a spare to boot.
Since about 1986, I have loaded 50,000 - 100,000 shells on the Grabber and 10,000 plus on the 9000 G without changing the collet. I put anti-seize around where the fingers are compressed on the down stroke and give it a little shot of Rem Oil from time to time.
I keep a spare collet handy as you never know when a collet might break but, properly lubed, they should last well over 50,000 rounds.
IMO, the MEC Sizemaster, Grabber and 9000 series presses have the best resizing mechanisms. I don't load steel hulls but if you do, get a MEC.
Curt; When hulls were tough to get in the 60's I got a lot of high brass rem's that were shot in very worn guns from the power plant.I had to use both hands on the handle off my mec 9000 to reload them.After 30 or 40 years and many thousands of reloads I had to replace it.Imo if you load low brass hulls and don't set clear down to factory specs I would bet they would last a lifetime.
