[QUOTE="7mmTikkaShooter, post: 1846274, member: 92915"] So I’ve got to share this with everyone. It’s a bit long so hang in there. I too was looking for some sort of temp stability numbers to no avail and then I stumbled into something. If any of you have played around with Hornady online 4DOF ballistic calculator, which I’m sure many of you have, then you would know there’s a section for inputting ammunition. What’s interesting is there’s an option to “Adjust Velocity for Temperature Sensitivity”. Just a little toggle option but by turning it on you can then select from a list of powders. Of course it’s still a limited list but there are many of the most popular listed. Here’s where it gets cool though. Below the powder selection box is another toggle option to “Use Custom”. This is in place for those who have done their own testing and have a specific FPS/degree number. By toggling this on and off you can see what number Hornady defaults to from their data. At least I’ll assume it’s their data but if not it’s likely from the powder companies or some reputable source. Either way, it’s a good starting point for you if you need to know temp stability numbers. [/QUOTE]
