@Professor Mawla thanks for bringing this question /topic up, it's really interesting and fascinating to see what others dream rifles are.
for me the first rifle would be a nice English droplock double in .577 nitro, build by either Westley Richards or Purdey
the second rifle i would love is a well build, high quality, and reliable rifle build with the original M98 DMW Argentino action in 9.3x62 , i would have this rifle build in the renowned gunmaking village of ferlach in the Austrian alps.
my third rifle would be a beautiful single shot "kipplauf" rifle also build in the Austrian gun making capital, ferlach!
i don't know what it is but some thing about a beautifully build petite single shot rifle (kipplauf) i find very attractive and fascinating
