I didn't see any evidence of shattering, Uncle Nick, penetration and exit wound size were almost indentical to another deer hit at almost exactly the same angle and in almost the same spot with a Hornady 30-06 handload I've come to know and trust. Only difference was a bit more blood-shot meat with the Hornady bullet. Both entry wounds (center chest) were very difficult to find, never really did find the entry on the doe made by the RD bullet. I don't think the bullet shattered but would have loved to test it on a nice big hog, just to be sure.
I'm going to try AC 45-70 bullets again someday but I have a good supply of these on hand.
Yes, LAH, cast bullet hunting is a fascinating and frustrating endeavour.
