You are absolutely correct. I'm just testing the waters. I'm open to trade suggestions. I've got both Promag and Ruger 10's for my RAR. The 20's are a little weird for a bolt gun. PAX.The cost on these mags is nearly the same. To be more fair, I think you should modify your offer to 2 - 20's for 3 - 10's. IMHO. And those 10's are going to be hard to pry out of low cap Blue state owners. Good luck.
