Just picked up my 300 Win Mag barreled action today and was checking the throat. I get a OAL of 3.590 using a 208 to reach the lands. The AI mag will allow for ~3.68 OAL. Question is, should I seat the A-Max to the lands, or leave ~.01 jump? Not sure if I need to leave a slight jump with a magnum cartridge, or if it will do better with the secant tangent ogive touching the lands.
