[QUOTE="7MMMagnum, post: 2324241, member: 39395"] I just read some test reports from an independent firm that tests lot to lot consistency of Hodgdon powder. I gather it is military sponsored. They tested H4831 in both a 25-06 and 300 WM with 6 different lot numbers. Published numbers ended up with 111 fps extreme difference. Well go figure. Hodgdon’s claim of lot to lot consistently may not be all what they claim. Authors of the study recommended starting from scratch when changing lot numbers due to safety concerns. 40 yrs of loading using Hodgdon powder and I have never experienced the extreme difference in lot numbers. Now I can say I have. Witness 200 fps between lots. Looks like I got a hot lot! It is gone now! [/QUOTE]
