Looking at the fragmentation table, there seems to be very little difference between these two in the 16" platform I have in mind. My new no-ban upper will be a cmmg 1:7, so I can now handle each. I already have a fairly large stock of the 68gr., because I used to only have a 1:9. Does it seem worth it to ressupply with 75gr.? How much difference do these two even have terminally?
