I am 2 for 2 with the 295 grain Hollow Point Powerbelt, pushed with 80 grains of 777 loose powder, out of my Wolf. Last year, (my first year hunting with a ML) 50 yard shot at a doe, she dropped in her tracks, and just last week, about a 40 yard shot at a doe, and she only ran about 25 yards, and was done. The main thing with the Powerbelts is, dont push them too hard, 70 to 80 grains of powder will do the job nicely.
