I usually use CBC 77gr OTM for 'serious purpose' ammo, but I have a considerable amount of the ADI 69gr SMK load that SG Ammo imported a couple of years ago.

Would this be acceptable to use in lieu of the 77gr SMK for keeping in a home defense carbine? Longest shot would be less than 50 yards.

This ammo is laser accurate and 100% reliable in every (4) uppers I own.
