Need to let you know that although I have not used rifle scopes on Contenders or Encores. I have used rifle scopes in the 20-24 power range on XP-100's and the MOA Maximum (Falling Block Rear-Grip Specialty Handgun) from cartridges in 260 Rem. to beyond the 300 Win Mag. class with success. Priimary cartridges have been 260 Rem, 284, Win, 6.5-284, and soon to be 7mmWSM. The 7mm WSM will have a high magnification Leupold Variable on it as it's primary scope.
My uses are for bench use at short range (100-200 yards) and long range (1k and beyond). Yes, I do pull away from the ocular, so I do not see a full field of view and these barrels are braked or ported.
