In my experience all the bullets mentioned work on deer from the .257 Roberts, whether up close or far away.
Have used the 115 Ballistic Tip as close as 30 feet, and much further than 250 yards. It worked great at both extremes..
How did the 80 grain TTSX work for you?
I shot some of them in the Roberts and 25 WSSM, but never found an MOA load in proven MOA rifles.
