I don't know for sure how much Hodgdon does as far as pressure testing, I've pretty much accepted that when they publish a pressure they did a test, at least the low and the high.
That being said, any ballistics program is only as good as its inputs and algorithms...
For QL and Grt it's known that they have some difficulty replicating performance of shorter, fatter cases like grendel and 6Arc... for either one you have to tweak things like actual case volume and sometimes other values.
So yeah, which one is accurate?
For Hodg I give them some benefit of doubt, bearing in mind that their results are also results from their gun...
Which load/bullet setup are you looking to start.
Most of the guys on here have trusted/used Hornady as being fairly accurate to start with, bearing in mind you might be using a non-hornady bullet.
For my new trials I try to get my start from Hornady data as much as I can do it.
Ex, for the 90 gr Sie Tgk I use a ladder from the Hornady 87 gr Vmax data. That sort of thing.
