For flat/round nosed bullets, the Barnes 150gr 30-30.....it may be the only Barnes I am enamored with. No, it's not 'needed' in the 30-30, but it is anecdotally more emphatic for bang flops from the 30-30....and I load it in my kid's 308, and it's nice, also. I like the FTX, but have seen expansion issues on occasion. 130 speers ain't bad, either.
