Thread: First attempt at necking down 308 to 7mm08

Damn it, I was in a rush so no didn't chamfer it. There's part of the problem. I was doing half a dozen other things after coming back from the range and dropping a bullet in was an afterthought. And no the seating die isn't set too low on this one.

When you actually site a projectile in the necked down 308 brass, then do the same with the 7mm08 round you can really see that the round isn't gonna fit in the necked down 308. It needs trimming on the inside. I'll measure it up tomorrow when I'm back over there.

My house is too small so my reloading room is at my folks in town.
