Found some #11 CCI caps at a local sporting goods store and bought 4 pac's. When I got home, found that two pacs were Magnum. I assume that the Magnum are hotter but they were two dollars cheaper/100. Have never used the Magnum's and know nothing about them. Can't be returned, 4hr drive around trip anyway. Paid $9/100 for the regulars and $7/100 for magnums. Appreciate any shared knowledge on this. Thanks.
