Thread: 7mm08 or .243 Subsonic round

Powder charge will vary a lot depending on the projectile, cast bullets needed 8 grains of Trailboss in my 308 but the sub-x bullets needed 11 grains.
The cast bullet loads were 7.5 grains in my other 308 and the 30-30, so 7.5-8 grains of Trailboss is probably a reasonable place to start in the other 08 cases with cast bullets
