That's why all of those "premium" brass manufacturers say to reduce loads by 10% because they know their cases are thicker. This goes for Alpha, Peterson, ADG, Lapua, I'm sure others too. It's always wise to reduce a load when switching a component.I think that cases are one major factor in pressure variables. I've been using Petersen SRP cases for my 6.5 Creed and pressures went way up as compared to Hornady brass. A load that was fine in the Hornady case locked up my bolt in a Petersen case. Bought some Alpha SRP brass and weighed it against the Petersen SRP which was substantially heavier, hence less capacity, something is thicker. I measured case thickness at the neck and both were the same so it has to be somewhere else in the case. Haven't done water weight yet but the empty case is certainly heavier.
I have a Speer manual I bought in the mid seventies, obviously powders have changed in 50 years but I like to look back at it to see how much lawyer influence has occurred. It's a lot.
So I'm loading for my tikka 300 wsm. I'm using 178 ELDx and H4350. Well at the bench tonight I looked at 2 different Hornady manuals to see what primer they recommend in their tests. While looking I referenced load data for 178-180 grain bullets. 10th edition list max at 63.4 H4350 and the 9th edition lists 65.2. Just wondering if any of you guys ever notice data changes over time with companies. I've often wondered why that is. I'm assuming lawyers have something to do with it and maybe marketing.

There's some non premiums that are real thick too. Federal comes to mind. I always reduce loads if they're on the warm side in Winchester brass if I'm gonna load with federal. It has notably less internal capacity AND it's less tough as well. Worst of both worlds!!!!! . Federal is some seriously soft brass in my experience, maybe they compensate for that by making it thicker?That's why all of those "premium" brass manufacturers say to reduce loads by 10% because they know their cases are thicker.

Yeah, idk how many cases of Winchester I've thrown out in a brand new bag because of a ton of reasons.OLD Winchester brass is still one of my faves. Best bang for your buck. But again, has to be older stuff, not their new "neck split special" production
But the stuff I have for my 300 win, 243 win, 270 win, and .30-30 win from pre-2000 years is awesome!Yeah, idk how many cases of Winchester I've thrown out in a brand new bag because of a ton of reasons.
A good Chrono and meticulous observation while working up charges is the only way I know to find the right load combination
Lawyer loads...
That's exactly what I feel like it is but didn't want to come right out and say it
