I have been there. At one time in my life I owned 100 or so rifles
Then as time went on I started to realize I was more of a hunter than a collector. I started selling them and bought better scopes, RF's and top end rifles and equipment. I now own less than 10 rifles. Some never get shot but have sentimental value, they will be handed down. It seems I am content with a 6 br, 300 win and a good 338 for all the long range work. And the 6 br has been collecting dust. This past season I sold off my beloved 338 LM in lieu of a LRMK that is in the works. So for big game season I was faced with only one rifle that was up to the task of everything from antelope to elk. My 300 win. I worked up a new load, shot it a lot, let others use it with my guidance, and you know what? I killed my biggest bull ever, also made my longest shot on game and every animal taken with this rifle (20) were one shot kills.
You have heard the old saying before " Beware of the man with one rifle, he probably knows how to shoot it"
You know you don't need them all. Clean the safe, keep what is most effective for your personal type of shooting/hunting and go bond with it.
Good luck! and never look back!!
