I can only speak for myself, but yes I feel that this shot was more of luck, but again if you read my post I said I'd rather be lucky than good.
Now with that said, I too feel that even todays modern muzzleloaders are not designed for such long range shots beyond 300 yards, otherwise the companies would claim it in efforts to try to up thier sales.
Now you seem rather upset about some responded posts, but now I'm calling you for some explanation. All three shots were over 300 yards, first one at 308 and so on and all shots were effectively placed. Your range finder confirmed this , but what blows me away is you got a reading , he took the first shot which was an effective one, he reloads as you get the second reading, he shoots with the same effective result, than the buck moves once again , you read range and again he places the shot effectively in the kill zone. Ok, its possible , but my experiance in muzzleloading is this, after every shot the gun gets harder to load more so after 2 back to back shots. Now this buck must not really have been moving after being hit effectively from the first shot because not too much ground was covered which is very possible.Again I ask as I am serious about wanting to know , but what is this set up ? Scoped inine shooting what charge and bullet? You posted this thread were there are some very experianced muzzleload hunters who take great pride in thier abillities with smoke poles and you write about shots and distances that are un heard of, so don't get upset or excited when asked about it. All hunting that ends in successfully tagging an animal has some luck involved I don't care who you are , thats why I said I'd rather be lucky than good....Step out of the box your writing from, read the posts and then you'll see why the questions come about, its not out of disrespect I'm sure you'll see.
