I've run 120 BTips in mine at one point, but also had one nuke on a shoulder knuckle. Not for me cause I do eat it all. They don't fly very flat either in my world when started at 2700, which is why I just went back to the 243 or step up to the 30-06.

If I were going to go back and run the 260, I'd go no less than 22" but would prefer a 24".
