In a Semi-Auto I know you normally have to use high FPS shells to break in so that you can use regular shells without problems, since this is Mag Fed would you still have to use high shells first still?

Hi Joseph, yes sir, it is the same for magazine fed. Use high velocity shells, at least 1300 fps. 
Stay safe & have a great day!

Hello Joseph,

The magazine system needs to be properly broken in, as magazine-fed semi-autos often require a little more attention to ensure smooth feeding. With a magazine-fed semi-auto like the Mag12 PRO, the primary concern would be ensuring the magazine and action cycle correctly with the ammunition you plan to use. High FPS shells (typically 3-inch Magnum loads) can help the gun cycle more reliably during the initial period by providing more gas pressure or recoil energy for the action.

Also please remember cleaning the firearm regularly during the break-in period is essential, as higher-powered shells might leave more residue or carbon in the gas system.

Hope this helps. May you and your family have a wonderful Happy Holidays Joseph!
