Excellent choice of bullet no better !
I haven't loaded jacketed bullets for the 30-30 in years. I've gone to cast bullets in my 30-30 rifles. Back then though, my standard load was whatever 170 gr. bullet I could find and 30.0 gr. of IMT 3031. The loads killed deer just fine and the rifles liked the load.
