I own a bunch of duplicates, or close to duplicates, and I have great reasons for all of them!
.300 Weatherby Sako AV & .300 Win Mag Sako 85
-Sako 85 built as a bean field rifle, 26" barrel, super heavy, not practical for walk/stalk
-Savo AV shorter barrel, lighter, great walk/stalk or hunt the world rifle
Summary: Strong argument
.416 Rigby Sako Brown Bear, .416 Ruger African, .416 Ruger Alaskan
-The Ruger African was purchased for my first Safari, and I needed a budget friendly rifle
-The Sako 85 because it is a nicer rifle - and they were getting rare
-The Ruger Alaskan because - well at the time you couldn't find them, and I wanted it - of course they are ubiquitous now
Summary: Starting to lose control
.375 Sako Kodiak, .375 Sako Brown Bear, .375 Ruger Alaskan, .375 Ruger Mossberg Patriot
-Sako Kodiak because it was my father's, but I took it on a memorable hunt, and now it's mine.
-Sako Brown Bear because I needed to replace my father's rifle
-Ruger Alaskan because I need that extra 100 fps for a brown bear hunt
-Mossberg Patriot because it was $300, and "fuck it why not"
Summary: You need to seek professional help
9.3x62mm Sako Black Bear, 9.3x64mm Mauser, and 9.3x66mm Sako Grizzly
-The 9.3x62mm to get you hooked, and I did end up killing a monster black bear with that gun
-The 9.3x66mm because they are super rare and I "may never see one again"
-The 9.3x64mm because it has the most horsepower, and "she'll never know the difference"
