H4350 lot to lot

[mrbig]

I been getting what I can and have a few cans with different numbers,,loading 42 grs with a 130 VLD in 6.5x47 ,,the first can I did load work up with 42 grs was up in the shoulder but not even close to being in the neck,,the next can 42 grs comes half the way up in the neck,,I have not shot any of these yet and loaded 25-30 before I thought anything about it,,the brass is the same and was all shot the first time with Varget and were all sized the same,,I was not seeing any pressure with the other lot number but am getting 3,000 fps from 28 inch Bartlien barrel with a long throat,,the 130`s are seated to 2.865,,

I never noticed a volume to weight change between lots before and wonder if I need to back down and work back up,,I went up to 43.5 before getting real pressure signs but am aware that the x47 Lapua brass with the small primer may hide some pretty high pressure,,

any thoughts??

Mix all that you have so you get one custom lot, I do this all the time and with the powder situation being what it is I bought 12 lbs from 5 different lots, I mixed them so that I would not have to do LD all over each time I cracked into a new lot.
