I was piddling on my bench today and decided to section a bullet. A common .30 caliber 150 grain Hornady SST, #30302. This bullet is marked as an Interlock bullet and I wanted to see if I could find the Interlock. Just about the time I finished sectioning the bullet, my son came into the shop and we looked at the bullet with a jeweler's loup. He tells me that he can see the interlock, but my tired old eyes can't make it out, even at 10 power.
So, I decided to take out the camera and see if I could get a picture.
Maybe when I get some quiet time next week, I'll polish that surface and see if I can't get a real good picture. These are great, excellent bullets and they fly nicely, but I'm darned if I can make out that ring.
