I have always wondered what benefit there is to square section over round?
Didn't the first HW 97's in .177 have square section springs in them?

I put one is an HW80 once and it could shoot through engine blocks.

I'm sure they'd make excellent piston return springs in elderly diesel engines.
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
Cheers ST I shall try to replicate my tinkering this winter.
Yep, increasing swept volume slightly but, and much more valuable, increasing efficiency so as to be able to use less spring should be the aim, resulting in a much more pleasant powerplant and less stress to the internals.
