BPS - I forget what load I used in my 7-30 but I do know that I used Hornady 120 gr SSP (Single Shot Pistol). I shot 2 buck with those bullets and they really did a number on them. But I was careful not to hit the shoulder because of their thinner jackets.
Also, you can run 30-30 brass into the sizing die and then use a light load to fire form the shoulder and have them formed to your chamber.
