Thread: 300WM Seating depth

Hi all,

I'm shooting 208 gr ELDM from a Bergara B14 which I find has a really long chamber. My OAL is 3.62" (pretty much mag length) and I'm still about 0.050 / 50 thou off the lands. The accuracy is OK for hunting, but not great - just under 1MOA. I've ladder tested with 76.5gr ADI AR2217 being the preferred load. Federal magnum primers.

So I want to come back to the ADI book length of 3.42" which has a book max of 78gr 2217.

Can anyone run me a test load on Quickload at these two seating depths with all else staying the same? I can't help but feel that even 76.5gr is going to be a compressed load given the length of the 208 pill. All else fails I'll just work up from scratch again.
