My problem is that arthritis is getting into both my thumb joints such that I can no longer seat primers with one hand & when I use two, I lose the sensitivity to feel the primer in. I realised that this was the case when the spreads on my best 1200 yard loads went from teens to over 30 fps.
My answer was to buy the K & M with the dial gauge head & "sight" the primer into its seat, rather than feel it in. Even so, I find that the mechanical advantage of the handle is j-u-s-t enough for me to be able to seat Russian primers into new brass. I guess the main thing going for me is that my loads are consistent again, as long as I clean out the primer pockets perfectly so the machine measures the pocket depth properly.
I can see that the Forster coax has the potential to give me the leverage I need to seat (but with two thumbs, my Sinclair did that), but how is it for sensitivity? Can you feel the primer bottoming out?
I need to make some plans for my presenility.
John,
welcome to my world! My hands have been banged up so many time thru the years (work related) that I just cannot use my thumbs for leverage anymore. I can seat about a half dozen primers with a Sinclair tool, and then I'm done. I think I've used about five or six different devices over the years. I never liked the Lee or the RCBS. Settled on the K&M in the end. I did make a gauge that uses a .00025" dial indicator to measure the distance below the face, and another to actually measure the primer pocket depth. The one thing I was shooting for was consistency in seating primers. I found the old style Forster that used the shell holder instead of the sliding jaws worked great. It would set primers within .0005" very consistently. At the range I prime with a K&M, and it works for me. Mine does not have the dial indicator, and see no real need for it. And I see similar results with the K&M and the Forster. I sold the Sinclair gadgit a long time ago, and never looked back.
