I’m helping my sister in law clean up my deceased brother in laws stuff. He had a Dillon 550 set up with 5-6 caliber heads for reloading. Also has some spare parts. I have zero knowledge of Dillon. She want to sell everything as a set. What is a fair value? She also has 2 Winchester 94 xtrs in 356 and 375, both new in box. She wants to keep one for my nephew. Which one should she keep? Thanks in advance.
