The reason the Ballistic Tip is relatively tough is the very thick base of the jacket. The Varmageddons are uniformly thin jackets, and I'd bet the plastic-tipped version would work for your purposes.
Thanks for the response. I was not sure how thick the base on that 55 BT is, but I wondered. That load atomizes ground squirrels, but I have hit a couple of geese who did not even loose any feathers as a result. I actually do try not to hit any, but sometimes...
The 55 BT I can get easily locally and I was shooting what I had on hand. I am going to get online and see if I can find some Varmegeddon.
