Doc the reason they put disclaimers in the boxes is because they have no way of knowing if the person doing the reloading is following the charges in the books or if they think that 9.0 grains of unique does ok then 12.0 would be so much better.
I take responsibility for all of the cartridges i load.
They are not supposed to blow up what they are shot in,but there are those that will use the fact that they screwed up to sue and not take responsibility for their actions.
As for just shooting factory in guns,for a long time i did just that. ,knowing that the factory loads more that not would not blow me up.
As far as leaving them blameless for making a time bomb,one needs to have some evidence of that,ether by metal flaw or design flaw. Not in any of the posts about this has it been shown just what was supposed to have been the fault.
I do like 9.0 grains of unique with 200 swc in the 45 colt as shot in a colt lighting rifle. But would never use 12.0. Common sense seems to have fallen by the wayside a long time ago. Get what you can while you can no matter who is to blame or is no one to blame?
