6mm/300WSM loading data
 

Well, I finished a fellows rifle today in the 6mm/300WSM chamber.
He wanted to know if I had seen any loading data for that cartridge. Really hadn't been looking because I didn't have time.
I saw some limited ideas on the Beartooth Forum. I guess that if he can give me all the pertinent data I can drag out my old Powley computer and see what he might try to start. I guess there should be a computer version out there, but I don't have one.

Do any of you fellows know of a good computer program that does calculate loading data based on case capacity, bore diameter, barrel length, etc? He wants to shoot the heavy bullets and knows the barrel will have a short life.
