54g looks good. I wouldn't have thought those speeds would be over pressure.
I like the stock on that rifle.
I believe there's more in the boiler room on both the 175 and 180. I could probably slowly run it up until I did get some pressure signs, but I reached the target velocity I was shooting for, and two decent loads in the 175. I did have 53.5 grain sets loaded, but didnt get to'em. So, as they say, "Good enough for Govmint work." This powder is not even in Quickload.
The stock is a B&C Alaskan TI
