Thread: Pushing 308 to 300WM speeds.

+1 for Gordons Reloading tool. I’m trying to work up a 308 load which has no book value for, and I’ve used it for a baseline to understand pressures and where to find the limit. Ironically my real life chronograph figures are lower than predicted from the application, but it still a good place to be to understand where to stop. (Currently sending a 185gr D46 @ 2750fps)

I’d watched the UR video and did wonder how many people would replicate it without the basic understandings. I cringe when I talk to some handloaders that just load based on the group on target at 50-100M, without measuring speed or looking up pressure max.
