Are the .44-77 BN and the .44-90 BN viable contenders in modern Creedmoor

IMHO, the biggest drawbacks to the bottle neck rounds is the bad press they have gotten over the years. The lack of brass is another big drawback. The straight cases are cheap and plentiful as well as more different molds than one would care to count. I am sure anyone that makes cut rifled barrels will make one in any twist you would like. My guess is if more people would take the time to find a good load the bottle neck rounds would be more popular.
When you consider just how many different bottle neck rounds were produced during the BP era they can't be that bad. The straight cases were just a bit cheaper and easier to load so the bottle neck stuff ended up dropping out of favor.
I have played with a 44-77 some and so far it seems quite capable of getting the job done. Its just like any other cartridge you have to find out what kind of menu your rifle likes and feed it accordingly. Any quality barrel and ammo should shoot well. What happens between the shot you fired and the next one you are ready may be a determining factor. I have noticed with my rifle that it will build up a bit of fowling in the throat but if you wipe well you can eliminate that issue.
Seems that there are some out there that love them and the rest just haven't tried one yet.
