The other day I took some 500gn (16 BHN) black PCed boolits and drilled our the noses with a 1/4” center drill. I then filled filled the space with red PC and baked again. When done they looked pretty cool, but how will they preform?
Has anyone done this before?
How can I tell how much expansion I’m getting? I don’t know how much it costs, but think ballistic gel is out of my price range. I’ve heard of wet telephone books. Any other ideas?
How hard is PC? Do we know what it’s BHN is compared to the alloys we use?
Thanks
