I have used the 125 Nosler BT over 20 yrs in my 30-30 14" contender. The last doe I shot sounded like a bat hitting a watermelon at a measured 126 yds. DRT It was a straight on shot thru the neck and into the chest. My load is a little over max with H4895 and it shoots under an 1" constantly at 100 yds. I am going to experiment with the Hornady 125 SST this year but, that previous load does not need fixing. [est. velocity 2200fps +]
