“blow out both lungs and the heart too i”
XD XD... nice.
I thought about blackout but I am terrified to have it in the house because I have 5.56 as well.
Can you imagine picking up the wrong mag in the dark?
Put tactile references on the mags. Or use only metal for one and plastic (P-Mags) for the other. Or only have out what you need to load. If the .300 is out, don't have 5.56/.223 in reach and vice versa.
No. The gun may or may not cycle. Either option sucks.
I keep my nightstand gun fully loaded with one in the pipe just to avoid the kind of problem you mentioned.
We need to practice practice practice with our home defender so if and when the time comes you need it, your muscle memory from training will help you overcome the adrenaline of the moment. I also believe your weapon should have a good working green or red dot optic for easier target acquisition during a high stress situation.
