You keep throwing out pressure. Doesn't the 5mm Remington Mag have a max pressure of 39,000 CUP? That would seem to indicate pressure is not the issue in rimfire cartridges you seem to think it is. That is 22 Hornet level.
Keep your hopes up if you wish. I know the facts are inconvenient and all that.
In response to your question, no.
In response to your conclusion, Your spin on my assertion is sadly misguided.
In response to your implied equivalence of pressure level with the Hornet, no.
