Reloading information is avaialble on the Hodgdon powder website Hodgdon - The Gun Powder People
I have used the Hornady 150 grain .311 diameter bullet in my son's Mosin with good success. Reloading is easy, gives the quality control to you, no issues with corrosive ammuntion, and in the long run is substanially less expensive than factory or milsurp ammo. Some of the 7.62x54r ammo I bought as surplus was in fact rejects. After having to use a rubber mallet to open the bolt when using the ammo in my SVT-40, I pulled bullets and weighed the charges, great deal of varience in powder weight as well as seating depth of the bullet.
