Thread: First attempt at necking down 308 to 7mm08

Success!

I re adjusted my die and deprived pin, made sure to use enough lube, resized the round, chamfered it then whacked a projectile in. It measures up the same as a loaded 7mm08.

Having the de priming pin back in correctly managed to keep the neck thinner. In any caseit appeared to work. Now I just have to figure out if it is safe to fire it chambers just fine.
Empty 308, 308 resized or 7mm08 (and loaded with a 140g Sierra game king) and a real 7mm08 with the same projectile,
