Again, the Keith bullets I recovered from ballistic gel showed no wear whatsoever on the shoulder.
I expect LBT's to do a hell of a lot more than cut a bullet sized hole.
Sorry, I have no recovered Keiths from the fake ballistic gel gutpiles.
LBT's (the WFN's/WLN's) do make bigger holes when wound up. They'll also garner more powder space or (gasp!) a reduction in pressure with standard data. The LFN's mimic most Keith designs, since most have similar sized meplats and case intrusion, both of which respond with mild to wild loads. FWIW, the holes in and out with the Keith look like paper punch holes...the LFN's at the same speed don't leave holes any bigger.
