Most accurate .22 magnum ammo

[Mr. 16 gauge]

Just curious as to what you folks have found to be the most accurate .22 magnum ammo. I'm thinking about trying something new......rabbit sniping! The areas I hunt for bunnies are HEAVILY hunted state lands.....the rabbits become attuned to this late in the season and dart for the holes the minute they hear a car door slam. Walking them up with a shotgun is almost an impossiblity, so I was thinking about sneaking in to within 50-60 yards of their dens just before first light or right at dusk and taking them as they headed for or left thier dens. Since I am limiting myself to head and chest shots here, I am not really concerned with so much with penetration/expansion as I am with pure accuracy. Does anyone make a "match grade" .22 magnum ammo? Thanks in advance.
