[QUOTE="highdrum, post: 2041410, member: 13732"] Temp stability: the rate at which velocity changed with ambient powder temp. If you're using a very temp stable powder like H1000 , you may have a 20fps spread from 20° to 90° faster fps as temp increases. If using a known temp sensitive powder like RL33 you may see 75 fps spread across that same temp swing. All cartridges will be a little different. But start with a known stable powder, and do velocity testing at the coldest and warmest scenarios you'll be shooting in to know where your load stands. [/QUOTE]
