The only way you'll know is to work up the loads in your rifle looking for pressure signs. COAL, projectiles bearing length, chamber and throat dimensions all influence the result. I started my load work up at 42gr. It was an educated guess taking into account other loads I've worked up in my rifle, the fact my rifle is long throated and I started with a COAL way over the usual 2.800" quoted for the majority of 7mm-08's and 168gr projectiles.
