I have not encountered that problem in trimming many hundreds of cases - my cutters still trim the cases crisply and with ease. But there again, I only trim by hand and reload small batches at a time. I have a feeling that the Lee trimmer requires a light feed and rotation.I started out with the lee. It worked for a while and it got dull and rolled the edge over and I got inconsistent lenghts ...........
+1 on the Forster.
I bought mine over 30 years ago. After 10's of thousands of rounds there is still no perceivable movement of the cutter shaft in the bushing. I have had to send it back once to be resharpened about 20 years ago. I picked up a Wilson about the same time (20 yrs) and quit using it quickly. It just wasn't as fast as the Forster. I also use a cordless drill to power the cutting, just easier on the hand & arm when doing large quantities of brass.
I agree I started with the Lee trimmer it was killing me it was so slow. I got the Possum Hollow Trimmer for 223/5.56 and did about 2000 cases in about a hour and a half. Thing was like $30 at Midway and worth a lot more.I HATE trimming cases. I also shoot a LOT. I looked at the Giraud, the Lyman, the RCBS, etc. I settled on the Possum Hollow trimmers. I got one for each caliber that I shoot. I set it and forget it. When I trim, I chuck it up in either my lathe or my drill press for power. You can also use a drill. They are fast and accurate.
LOL.... That's gotta be the best product endorsement I've read yet...I have a Forester, if you can sharpen a pencil you already have the knowledge to use the machine.
