genehunter.....the 250 AB loaded by nosler were the most inaccurate loads i've tried....but i mean to say that they still shoot to about a 2.5" group at 200yds. from my CZ 550FS....they do land alot higher on target than anything else...but they do fly the flattest of them all....they seem to be a horse of a different color for that gun....every other loading from norma or nosler(286 PT) were more predictable on the target....bearit....
