The cocking angle has little to do with the power of the air gun and only determines the ease of cocking. A longer "swing" for cocking contitutes more leverage which makes spring compression less strenuous.
Though I'm not familiar with the internal differences between the Quest models (500 and 1000) I would assume that the 1000 has a more powerful spring in it which most likely consists of one made with heavier gauge wire and, possibly, of longer length. Unless there are major differences in the receiver length and piston travel I would also assume they are of equal size in terms of piston diameter. The difference in cocking angle would then be to eleviate the force required to cock the rifle should all this be true.
The cocking stroke in regard to the piston travel would be from the full forward position to the distance where the sear engages the piston plus a bit of overtravel to ensure that the sear will engage fully. There are no "stops" to make the rifle less powerful.
Not being familiar with the internals regarding the sear and piston between those models I would be a bit cautious in attempting to fit in a considerably more powerful spring in a 500 due to the possibility of weaker parts used for the sear and piston in the lower powered model.
Bottom line is....if you wanted a Quest 1000 why did you buy a 500?
I'd suggest you take Eddie's advice, do a nice tuning on the rifle and be satisified with smooth performance and some increase in power.
