As to powders. Not really too bad if you read the literature that is out there. I found it goes kind of like this:
RL-22/RL-25 high performance and they suck for temp stability and I have had loads fall off a node and shoot bad from a 30 degree change.
RL-17/RL-26/RL-33/RL-50 very high performance and known temp drift of 0.5 fps per degree F (per Nitrochemie who makes them in Switzerland). I find I can live with the temp drift which isn't too bad if I use common sense and develop loads near the temps I expect to use them.
RL-16/RL-23 appear decent for performance and rock solid with temp change per Bofors in Sweden who is the manufacturer.
H1000/Ramshot Magnum - tested by Barnes and shown to be very temp stable
IMR Enduron powders are also supposed to be rock solid (but that stuff is expensive as in over $30 per pound so you won't see me buying it)
