Try some of the Sierra 45 gr SPs
, Remington 45 gr SPs
(Crankylove's favorite Hornet bullet, also a 77/22), Winchester 46 gr HPs
, or any of the various 30-36 grain HPs or SPs (except the 35 gr V-Max), to get you a little farther off the lands.
Like UncleNick, I think it's the ogive on that bullet, that is giving you the issues. Seat it deeper (with a corresponding new load work-up), or try a different bullet.
