The 650N Mec reloader didn't come with a way to resize the Brass base of a shell. But, is there not a way to add a resizing ring and tube over the de priming pin assembly! I would think there would be away to accomplish this modtification. What have you seen in all of your years! I bought this at a garage sale, not looking at it real carefully as it was a clean as a new one. Thanks for your experience in this quest. Steve M.
Never seen a 650 updated for resizing, When I bought my first Mec650 back in 1968 they also sold the Mec Case conditioner. A standalone deprimmer and resizer. Several for sale on Ebay. I think I might still have one also. Only time I used it was if the shells didn't come from my gun. Try it out first that 650 will do a great job.
650s came with a PITA add-on re-sizer!! I threw mine away and kept my hulls seperated between my 1100 and model 12. Solved that problem.
I got an old size master stripped it down and used it for resizing & depriming; when I used to reload
