I have been doing some simple testing of some ADI rifle powders over the last week with some interesting results.

I was wondering if anyone can comment on the subject with personal experience.

Yep, have found the latest powder more Temp. sensitive. Unusual.
Also found the Chrony readings about 100fps. slower in the heat up here in CQ. Time of day can make a big difference. Unexpected.

100 fps is a lot. What powder were you using?
