Its the muzzleloader makers today with their 150 grain magnum BS load that ruins accuracy and bullet performance. They didnt have these so called magnum loads back in the old days and you still dont need them today.
I recovered between 6-8 225 powerbelts when i was shooting 200 yards some months back and they mushroomed nicely with 100 grains of fffg goex and lost almost no weight at all.
I think that 100g is much too fast for the 225g PB, the chart for PB says that is 1720 fps, not good for a PB. Chap Gleason
