I think you made the right decision although I also understand the better selection of bullets for a .50 over a .45. If deer is the only game not elk the .45 is just fine. As for recoil; I am fairly recoil sensitive also and have added Limbsaver recoil pads to all the muzzleloaders that I shoot with anything over 80gr. of powder and 300gr. bullets. The bullet weight is definately one of the main causes of recoil. Dave (Cayugad) gave you all the right information. This likely will not be the last muzzleloader you buy but I think at the price it is a very good start. Look for a Limbsaver pad!!! You may have to go with the grind to fit but there may be one that fits close if they do not have one specifically for the rifle.
