I have come into possession of 20 rounds of 300 win mag reloads. the plastic container has the following written on it.
75-4350 x 180 Nos/Par. I have interpreted that to mean 75 gr of IMR 4350 powder with a 180 gr Nosler partition Spitzer BTSP..
My Speer reload manual lists the recommended powder for that bullet wt as 68-72 gr. I have searched the web for reload info and have not found any relating to 75 gr.
I am not sure where to go from here. I don't have a 300 win mag rifle and was going to sell these 20 rnds either on Armslist or at a gunshow. Canj't do that without better reload info. Any help?
