I have a Pursuit LT .50. I bought one of the first ones available and the trigger was an absolute nightmare. I finally did my own trigger job as I bought the rifle for my Brother-in-law to get him to go elk hunting with me. We did not have a lot of time to develop loads but trying to keep it simple for him (new muzzleloader guy). I tried one 50gr. Pyrodex pellet and one 30gr. pellet and the 295gr. Powerbelt aerotip. We got some 100 yard groups less than 2 inches and decided that was good enough. Unfortunately he did not get his elk. I got mine but with the Omega. I also tried some American Pioneer powder which shot well in the Pursuit but he didn't want to deal with the loose powder. We only tried 295gr and 300gr. bullets as for elk that is my minimum weight. The Hornady SST bullets shot well also but were a lot harder to load than the Powerbelts so for him we settled on the Powerbelts.
