[QUOTE="Engineering101, post: 1162656, member: 63138"] Turns out RL-17 (and its brothers RL-26/RL-33/RL-50) all made by Nitrochemie in Switzerland are considered to be moderately temperature sensitive. They are rated for 0.5 fps velocity change per degree F of temp change. That obviously assumes some standard load in some standard rifle and your mileage WILL vary. RL-23 on the other hand is supposed to be flat out temperature insensitive and this is made by Bofors in Sweeden. It is based on the same formula as AR-Comp which is likewise temperature "insensitive". Bottom line, if you thought RL-17 was bad, you haven't seen bad. Powders like RL-22 or RL-25 really suck for temp stability. Those are the reasons Alliant came out with RL-23. H1000 and Magnum are "insensitive" to temp changes and there are others that have come out recently like IMRs Enduron line. Personally I don't have a problem with the temp sensitivity of the RL17/26/33/50 lineup as you do get some pretty good performance boosts from those powders. You just have to be aware of the powders limitations and not do something with them that they can't do. [/QUOTE]
