Those are definitely not .22 LR. They even look too long to be a .22 Magnum (but that is probably what they are), which is also a rimfire, but the similarities to the LR end there 
From some web site:
"The .22 Magnum is a much more powerful cartridge than the .22 LR. At 100 yards its 40 grain bullet is still carrying 156 ft. lbs. of energy, more than the .22 LR develops at the muzzle (compared in 22" barrels). The flat shooting WMR can be zeroed to hit +0.6" at 100 yards when fired from a scoped rifle, and will give a point-blank range (+/- 1.5") of about 124 yards."
