Have shot a lot of muzzleloaders over the years and my experience the knight has been the easiest of any of them to get to shoot good.I have 6 muzzleloaders now only one knight mK85 that I have had since it came out,and it shoots very good.Haven't shot any heavy bullets (above 250 grs) since I shot sidelocks.Haven't had any problem shooting light bullets(250 and under) in any of the knights I have had,one of my favorite bullets in my ruger and a knight I used to have was a 185 gr nosler,it would allmost take a deers head off.
Had a knight 45 cal disc,worked up a load using the 225 gr power belt took a deer @155 yds with it.Sold it to my brother he took 2 this past year with it using the 195 gr powerbelt.
Since the sst have come out I use them,they work on a deer and shoot accurately too.
