[QUOTE="MagnumManiac, post: 1225995, member: 10755"] I worked for ADI, the company here in Australia that produces most of the Hodgdon single base stick powders. They go to huge efforts to keep the burn rate within 3% of what it should be, humidity and temp are controlled during manufacture, if it fails the 3% swing, it is blended and made into a commercial powder. Canister powder, which is what we buy HAS to comply by LAW to be within that 3%. I have seen swings of 100fps myself with H1000, Retumbo and H4350. This is less than 1% swing in burn rate, which is pretty good. You also have to understand that atmospheric conditions, not just temperature can and does affect velocity and pressure within the gun system. Cheers. gun) [/QUOTE]
