CCI Small Rifle Magnum Primers

[BS56063]

First time posting so be patient. I Stumbled across some CCI Small Rifle Magnum Primers a couple of weeks ago. I thought I could just drop the loads about 10% but I don't really feel like redoing my loads, So I am wondering if anyone out there would want to Swap out standard for my Magnums I have two box's

Just to be clear, you have 2,000 CCI 450’s and are looking for 400’s? I know I have one box of 400’s laying around, not sure if I have two.
