Groovy!
Thanks, Sieger,
I just brushed up by checking with a G. Hemrotin e-book; yes, I'd forgotten that, of course, the upper edge of the cartridge's rim is the contact point under pressure. My thought was mainly to reduce the friction within the mag. I'm not a reloader yet, but had heard about the lube groove's exposure as a concern other reloaders had. I figured that the slippery strip/shim's dimension must be accounted for to maintain the cartridges' angle within the mag--gotta be as parallel to the upper side of the follower as possible. I reason that the optimal precise cartridge length would be changed by the new internal geometry, and hypothesize that shortening cartridges by seating the bullets further in would be a way to compensate for this decrease in width of the mag. It occurred to me that doing this might also address the lube groove "problem" I'd heard about, probably right here on this forum.
