Even the slow twist should be able to handle the 80 gr. TTSX, and that bullet will handle elk and everything smaller.
I shoot the 75 grain Barnes Original X in 1-14" ROT 250-3000 and 25 WSSM barrels, but the 80 grain TTSX is just a little too long for a 1-14" ROT barrel, even when pushed at 25 WSSM speeds.
