.45 ACP and AA No. 2 Powder - data has changed

[Walkalong]

but I saw no signs of excessive pressure on the cases

At .45 ACP pressures, you won't until it is way over pressure..

Just as an aside, I've found some Western Powder data has changed with time. I started using True Blue around 2008 and as new data came out for the 9x19, Western Powders reduced the max charge.

So, I would not be surprised if other data was reduced here and there. The reasons could be many and varied.

I have this load map book. I wish I had purchased the whole series of them for all the calibers I load. I liked the format/layout of it.
