Hi William and welcome. No Sir. For safety and warranty reasons, I would adhere to Heritage's recommendation on standard SAAMI pressure loads. Cheers, stay safe and enjoy!

No.

Hi Willian, no sir, these are not standard pressure cartridges. According to the owner's manual "The use of reloaded, “remanufactured”, hand-loaded, or other nonstandard ammunition voids all warranties. Always use ammunition that complies with the industry performance standards established by the Sporting Arms
and Ammunition Manufacturers Institute, Inc., (SAAMI)"
Stay safe, & have a great Memorial Day weekend!
