I came to my own conclusion a year or more ago when I looked at the Ballistics By the Inch website. The site only goes down to a 2" barrel on 22 LR and 22 WMR but based on muzzle velocity only.
CCI 40 grain the velocity of 22 WMR is only 100 FPS faster the LR. Might make a little difference in performance but not significant..
Out of the 1 5/8" I basically have figured basically a tie in terms of performance at the muzzle..
Unless they have updated their info, they used regular WMR ammo, not the stuff specifically designed for short barrels. The difference is greater now.
