VV N160 differences

[giumau1]

Did anyone notice any substantial difference between pre-2020 and post-2020 VV N160?

the 'new' one seems to be significantly hotter and I started having flattened primers with the new one even with a pussycat load in 6 creed, Lapua SRP. I didn't have the chance to chrono it yet but it seems that speed went up quite a lot, from 2930 to 3000 approx all else being equal. 'old' powder was properly stored and wasn't older than 2019. Unfortunately I trashed the can so I can't track down the Lot. Thanks a ton.

Pretty common with many powders.
My current keg of H4350 is different than all the other H4350 in the past.

that's why it's always wise to work up again the load. Honestly I did not this time because I choose a lower node, was simply not expecting pressure signs

Yea
My previous H4350 load was mild and heat tested, new powder was 80-90 fps faster.
No pressure but I’m sure it wouldn’t pass the hot day test.
