Thanks to all! Rifle will be intended for Kansas deer. The rifle is a tweeked Mark 5, and I am using Norma and Weatherby brass.
The 7mm Weatherby seems to shoot well right at the upper pressure limit with a full house load. Not saying to start at a max load, however. Not trying to be Captain Obvious here, but watch your case capacity with different brands of brass. I have even found some weight/vol variation in newer and vintage Weather brass. Hornady and Remington brass have very different case capacities than the Weatherby stuff. Happy Trails
