Greetings @Tentman and @tetawa.
With the 8x57 in your lovely sporter you are using .323 projectiles out of necessity and likely loading to low pressure. It is likely that the .323 projectiles are quite soft for the obvious reasons. For use in a .223, as Tetawa is considering, correct projectiles are available. I suspect that they are made by Hornady rather than Speer and if so are flat base. Quite different than the NATO projectile I mentioned. I stand by my earlier statement the for the .223 and the projectiles could be dangerous and should be avoided.
Regards Grandpamac.
