My load book says you case length is good to go. 2.255 is max.
As noted, check max OAL using a non-primed no powder case, and the bullet you intend to use. I find splitting the case mouth makes it easier. Some guys try to get the bullet to within a few mils of the lands, but I think that is not needed and, if you have any variation in loading, can be dangerous. In 348 Win, I load .025 short of max and am shooting 1" groups at 50 yards with iron sights.
