My only experience with Silver Tips has been round nose 190's in .303 Savage. They've killed deer and caribou wonderfully for me.
When I was a kid, I had two rounds of.30-06 with 150 grain Bronze Points. I used them to kill two woodchucks. One was standing up facing me at about 20 feet. I hit it square in the center chest, it fell forward and commenced to run furiously in about a thirty foot circle, got back to where it started, realized it was dead, and collapsed. The second one was running straight away at about fifty yards when I fired. When I got up to it the head and a strip of belly skin were the only things that hadn't completely disintegrated.
