IMR 4451 batch consistency, question

[fiftybmg]

I'm at the end of the can of 4451, and I see the new one has a different batch number.

How consistent is the IMR 4451 batch to batch ? Do I need to to load dev ?

I expect not to see much difference, but feedback from anyone that has crossed the batch number line is appreciated.

I normally back down at least 2 grs and chrony the loads working back up with the same components. If your vel is basically the same then you should be good to go. JME
