I want the shot to disintegrate at hit, avoid ricochets...
Oh it definitely will do that. In fact, if it strikes the ground or a tree branch it is likely to disintegrate instantly.
This is basically how I make them. Except I have a 1/2" holesaw chucked in my drill press to open the top.
Here is a wax slug into ballistic gel.
And here is Paul Harrell testing wax slugs. I love all his videos.
Take care. Tom Worthington
