Good plan. I third the notion that you should spring for a Rockchucker press instead of the smaller Partner press. The RC is ten times the press that the Partner is and isn't that much more. Even a used RC would be a better option. You're loading some pretty tall brass there with the 270 & /06 and your results will be more uniform, and done with less effort with the RC.
Don't scrimp on the scale either. The choices you make at this point will set you up for either frustration and a longer learning curve, or trouble free uniform results with a shorter learning curve. Good luck, and welcome to the madness, lol.
