Should I use 70 or the temperature it is at when I bottle, probably around 40.
The reason the priming calculators ask for the temp is because they're trying to calculate the residual CO2 leftover from fermentation. Since that CO2 will be lost if the beer is warmed after active fermentation, but you won't increase the redisual CO2 by chilling it, you always need to use the highest temperature the beer reached after active fermentation ended. For your situation, that would be 70°.
Hope that makes sense.
