Have found success with my Contender.30-30 using Reloader 15 with Sierra 150 FB spitzers and Hornady 150 RN. Book data is good but you will likely experience frame stretch at max load levels. Ballpark 2300 fps with the Sierras is good for sub 1/2" 100 yd groups in my gun using an El Paso Weaver K2.5. Either bullet does good work on hogs and deer.
Frame stretch is not fatal but extraction can be difficult. Cast bullets might be the schizzle for this rig but I've not tried them yet.
