I don't personally have any experience with the 6.8 SPC in a Contender Handgun. However I have had a few different 7-30 Waters Contenders over the years. Considering the case capacity and weight of the bullets commonly used in the 6.8 & 7-30 I would think that what applies to one will apply to the other.
Recoil is quite mild with the 7-30 Waters and accuracy of the 3 barrels I have had has been right at the 1" mark for 5 rounds at 100 yards from the bench. I have also found the 7-30 Waters to be easy to load for, and it was not to finicky about which powder I fed it.
I know I didn't answer you question, but I am thinking all of the above will also apply to the 6.8. A buddy of mine in Texas has a couple 6.8 SCP Handgun Barrels (I think one might be a 6.8 Improved if I remember right). I know he has been impressed with the cartridge but I don't have any specifics as per what loads he is using.
Merry Christmas
