You can see bullet impact (and sometimes trace) easier with a bolt, which becomes more important when range estimation and wind are part of the equation; because then you have an idea of what you did wrong when you miss.
That may be true for you, it does not however indicate accuracy potential. I have found it is far easier to get an AR accurate than a bolt gun. I built a 1/2 MOA AR and like a fool traded it during a fit of I gotta have THIS gun.......
