My trimmer came in, so I modified a few yesterday evening. I drilled the pinched tip out with a 1/16" bit, then trimmed the bullet's OAL down by .050" opening up the meplat similar to that of a SGK. Now I just have to test them, but won't be able to do that for another couple of weeks.
In theory, it should work as planned considering that the bullet design between the SMK and SGK are basically the same other than a few tweaks of the SMK for better ballistic performance. You can see this in the cross section comparison pic I found of the 2.
