[QUOTE="Byrdman13, post: 3081803, member: 128964"] If you are only going to shoot 140-150 grain bullets a 7.5 twist isn’t really needed but should shoot fine. 7.5 twist would only limit you on velocity if you tried pushing a light cup and core bullet to high velocity. The bullet rpm tends to get a little high and the bullet starts to come apart from the rotation. I have a factory x bolt 7.5 twist 24” 270 and it shoots great. I’ve been pushing 165gr Nosler ablr to 2895fps and it works great. The heavy for caliber bullets is where the 7.5 twist shines. [/QUOTE]
