I recently acquired all of my Dad's old reloading equipment. I would really like to start to loading my own .44 Magnum and these are his old dies. I'm 38 years old and I can remember us shooting loads from these dies when I was about 8 so they are at least 30 years old. There is no visible rust or pitting on them but there is an old greasy/waxy substance on them that probably needs to be removed. I would like to load 300 grain or 250 grain wide flat nose cast bullets for .44 Mag hunting loads. I was going to write a better description of the label and the dies but they say a picture is worth a thousand words. In your opinion, are these dies good to go?

Yep.

After cleaning they should be good to go. If you plan to load a lot of .44 I would invest in a set of carbide dies just so you don't need to mess with lube.

Yes they should load thousands of more rounds but they are not carbide so you have to lube your caseings.

If they were mind I sell them cheap but the money towards carbide set.

Well, they are about 15 years younger than mine and they still work quite well.

Carbide sizers are sorta nice but, used correctly, the older steel dies actually help cases last a little longer. Given the low volume of ammo most .44 shooters require I doubt carbide would make a lot of difference for you.
