Just my opinion, but, magnum rounds for HD aren't necessary. A good low recoil 2 3/4" 00 buck round with 8-9 pellets is more than enough. The extra pellets in a magnum shell just mean you have more things to worry about flying around your house. Regardless of what rounds you choose, make sure to pattern YOUR shotgun with the rounds you choose to use. Not all 00 is the same.

 

+1 on the patterning

 

Not quite in agreement with you on the magnum buck, but thats a personal preferenc

Thanks for all the information here. I have decided to purchase a pistol grip for my Mossberg Maverick Security so I can maneuver it through the house easier than with the standard stock. I feel that 6 rounds of 00 buck should be enough to stop an assailant or two in their tracks if I practice shooting with the pistol grip. My HD situations would only require a max range of about 25 feet; so I think the pistol grip will serve me well.
