Interesting bullet design and should be enough powder to make it squirt!

I have loaded this bullet over 13.5 grains of Longshot and I get 1650 fps. Very accurate.

Wonder how that Lehigh slug would work on wild pig.

I have no doubts on their performance. 

I used the 220gr 45cal on a doe from my 45 Raptor rifle. I know its not apples to apples but Was totally impressed with the damage done.

I have used the 150gr and it works great. Sadly, have never recovered a slug though. They are laser accurate out of mu Springfield XDm10 4.5 OSP with a 5.2" barrel.
