H4831 question

[TG-5150]

TG. The load was developed at around 4000 ft. Temp. was running around 50 degrees. The day I was shooting was around 70 degrees and elevation was about 4600 ft.
I never gave any thought to the fact that the powders were not from the same lot. And I doubt if they were even close. Was not checking speed that day. Wish I was.

I liked your quote because just a few tender yrs ago i didn't know about lot numbers with brass,powder,primers and bullets. I am chief "learns slowly".
the loads i developed at just over 2,000' for 3 guns don't work at 7-9,000'. The elevation in WY is insane. The loads were not off by much but were no longer "church".

Temp stable in Wyoming can be -35F or colder to 110F or slightly hotter in summer. That is asking a lot from one single pet load IMHO
