What volumn are you looking at ? It maybe worth going custom.

This is a 7mm custom made 175 RNSP (Non Bonded) projectile for my 7x57 made by a home operator in his shed in Queensland, Australia. Not being faniliar with how it is done I assume he is useing some kind of home press set up. Cannulation tools are avaialable from Sinclair and he can also bond the core if needed to for higher impact velocities. He can also make other calibres. (9.3mm maybe an option later).

I'm sure there are blokes in the USA who could do the same thing in 6.5mm with custom cannular and internal components for specific use at 6.5x54MS velocities.

I'll try and post a picture tonight of the recovered projectile from test medium.
