Unusual Norma bullets

Several problems with bullets that long.
Do you have room in your magazine?
If not it will take up room in the case that could be used for powder!
If you hang it out front you need a lot of free bore so its not jammed into the lands!
Yep, that can be an issue, depending on the setup. I loaded the 163 Chinchaga in my .257 WBY without any problems, as the .257 WBY has a long .378" freebore.
