If you have a 50lb per inch spring it requires 50lb to compress the first inch, then another 50lb to compress the second inch and so on as it's a linear rate, unless of course you have a variable wind, but lets not get overcomplicated.

A gas ram increases its pressure as the volume inside is reduced, so say you have a 50lb per inch ram it would take 50lbs for the first inch (huge ram I know ) the second inch would take 100lb and so on, so you would end up coil binding the spring trying to compress the ram.

not to mention the complication of trying to link both rigidly and then cram it all in the cylinder!
Mmmm....makes me want to bin my previous post!
