I own a XML and the gun is absolutely awesome. Not only is it ridiculously accurate, the fit and and finish is no different than my other custom rifles by Mcwhorter. Comes with Load data for smokless and load data for BH 209. I shot .5 MOA at 600yds. I have not taken it out any further yet.
Would I put it up against cheaper muzzleloaders, absolutely. However there is always a reason a gun is cheaper. It may not be due to accuracy, perhaps fit and finish. But I guess thats why they make work duty pick up trucks and luxury pick up trucks. If you are not on a budget, I would buy a Mcwhorter. I own 9 of his guns, and they all drill bug holes..
