I recently bought a .308 Remington 700 SPS Varmint and have been trying to work up an accurate load for it. I will usually barely insert a bullet into an unprimed case and insert into the chamber and let the rifling seat the bullet so as to work up a correct seating depth. I usually do the math and start loading the bullets about .035 off of the rifling. Trouble is that with this rifle, using 168 SMK's and new Win. cases, the case mouths are not long enough to properly seat the bullet. Guess I could fire the cases a couple of times and let the case mouths grow or try some 175 SMK's. Never was a problem with the 6mm Rem. or the 25-06. Any other suggestions out there?
