Anyone familiar with these? They make solids with a cutting edge. Supposedly superior to expanding bullets. I was talking to a PH on Facebook who was out patrolling for snares with a Marlin Guide Gun 45-70. He told me he was using a 225 grain Impala solid and runs that same bullet from the smaller antelope all the way to Eland. Since the cutting edge is not out on the tip I really don't understand how they work so well?
