I saw that too. Just assumed it was a typo or miss measurement.
Longshot seems to be linear in it's pressure curve. It's a safe powder.
At least in my loads for the 10mm and .460 Rowland .
A slight hijack.
Your experience with 460 Rowland loads and Longshot vs AA#7.
I just got a Rowland up and running and will be shooting some Super-ish loads this weekend to get a baseline. I'll be shooting Montana Bullet Works 250 LFN GC and Missouri Bullet Company 250 grain Pinbusters with AA#7.
This is in a 1911 platform.
