I love their bullets. I shoot an older knight wolverine with the #11 cap. I originally shot either the hornady xtp 300 grain bullets or the 303 grain bullets remington used to market, both jacketed hollow points over either 90 or 100 grains of pyrodex rs. They all shot so accurately I couldn't believe it. I shot 3 deer with these bullets and never found any of them. I was at the point of giving up muzzleloading until someone turned me on to these bullets. I honestly thing that mypowder/bullet combo weren't producing the velocitiesneeded for good expansion on the bulletsI was shooting. I called them and went all theway down to a 220 grain bullet(dead center 220 grain) over80 grains of777powder. Not only is this loadincredibly accurate (I only shoot about 50 yds, maybe a little more) but the expansion and knock down power is out of this world. The first 2 deer I shot with it dropped in their tracks. The last one ran maybe40 yards and left a blood trail anyone could follow.This is pretty typicalperformance from what i hear. Hopefully you will find the same performance. Go to their website, www.prbullet.com and check out their bullet selection chart. It will give you a good idea of what will perform well in your rifles rate of twist. I don't have any affiliation with their company but I will tell you they literally saved my muzzleloading career. I would have given up hunting with a muzzleloader if I would have lost another deer. Let us know what you decide. Thanks, Greg
