.250 because it's my favorite. It and the .257 Roberts are all the deer rifle I need. Early Ruger Tanger 250, 100 Speer Hot Core
Buck was heavy enough I didn't bother trying to load him, just slapped a chain on and drug him back to the house.
A very ...very nice "CLASSIC" rifle...an older tanger Ruger 77 in .250. A 70's gun if I had to guess the manufacturer date.
I found that dang rifle for him on the used gun rack of a local shop 10 or so years ago, called and asked him if he wanted it for the $400 sticker price. Never should have called him.
