Cannelure on Sierra M King
 

Has anyone attempted to put a cannelure on a heavy Sierra Match King bullet and shoot it into gel?

I am wondering if a cannelure would be enough to weakend the structure of the bullet and make it come apart for better terminal performance. I have shot a few 220gr Sierra Match King bulllets into corbin simtec in the past couple days. Although the bullets tumble, I am not overly impressed.
