I tested this bullet with two Pyrodex pellets a couple of years back. They shot pretty well and weren't too punishing on recoil. Tested them in wet phone books along with the 348 gr. Powerbelts. Good results. Front 1/3 of the bullet mushroomed nicely to about .80 caliber. The 348 gr. Powerbelt HP flattened like a pancake, and appeared to be on the verge of coming apart with the same charge. Some fellow hunters in this area have used this bullet on Elk and Bison with good results. Should be tough enough for the biggest hog that walks.
