Hi Dan,
Thank you for your email the other day. this muzzleloader has a 27" Bergara barrel in 1:28. I called CVA to see what the factory specs this barrel, .499 to .501. Designed to be .500 +/- .001 top of lands.
I have a Thor bullet size kit but have not used it yet, I want to use your 440UC or 460NEx bullet. Which bullet would be best in this gun for Elk? And what size would I order?
Also since I live in Idaho must use RWS 1081 musket caps, which powder would you suggest?
Thanks for your advice.

I will try to answer your questions to the best of my ability but you wont be getting the opinion of an expert. In 50 cal your 1/28" twist will handle about any length bullet I can imagine anyone wanting to shoot. On the .499 to .501 is that bore and groove diameters or is it the range of tolerance for bore or groove?
The bullet diameter you will finally decide on will largely depend on not only your actual bore diameter but also weather or not you will wipe between shots. A tight bullet may shoot good but if a quick follow up shot is needed and there is no time to wipe the bore that tight bullet may not seat at all. On the other hand a loose fitting bullet may move off its seated position on the powder if the loaded gun is handled less than gently and consistently held muzzle up. For these reasons it is hard to say what will be right for any individual gun without the formality of trial and error.
Ideally in a clean barrel .001 to .002" over bore diameter is good. This allows slight engraving of the bullet in seating. In a fouled bore that might not work so good. You have to decide if you want your bullet diameter to be right for a clean bore or for a fouled bore or a compromise of each.
As for your musket caps they are big and supply plenty of fire to ignite any type of powder you will choose. I personally prefer true black powder to any substitutes which brings up another point about your bullet diameter. Some powders foul more than others so the powder you choose will also have some bearing on the correct bullet diameter that will be best in your rifle.
The theme of this answer seems to be alluding to the ever so popular " it depends" and sorry I cant give a more precise response than that. Another popular response is " time will tell" and I bet that will prove true as well.
