300WM Throat recommendations
I am piecing together a Savage 300WM & on order is a Shilen Select Match 26" barrel. I was told I need to send in a few dummy rounds to figure the free bore needed. I plan to shoot from 168-208amax so they recommended a longer throat to accommodate the bigger bullets. I have always based seating lengths on the lands provided but dont really know where to start with a custom throat. I realize SAAMI has OAL at 3.340 & AICS mags can load 3.625". Any recommendations would be greatly appreciated!
