Camo, here is my first & only experience with Powerbelts (245 gr copper hollowpoints to be exact). Last week I shot two Deer in Georgia and I dropped them both on the spot, although neither shot punched all the way through.I only recovered one bullet which struck a doe through the spine and into the lungs and it retainedthe majority of it's weight to my satisfaction. I was shooting a CVA Optima/ 100gr of T7(2 pellets). To be honest, whileit accoplished the desired task, I felt that at least one of the rounds should have gone through & through.
