Every rifle (4 total) sits in my safe with a 30rd mag of 55g TAP in the gun, no round chambered. When I am home the safe is unlocked for quick access and when the kids are in bed, gone, etc. a rifle is usually in a room with me. After that I have a PIG plate carrier with 5 mags loaded with some good old XM193. Obviously that would be for things going full retard. Also in the safe is two more mags loaded with the TAP rds and two mags loaded with 64g Speer Gold Dot Bonded rounds.
For the tech side if it, I have found the POA/POI shift between my XM193 and 55g TAP to be very minimal out to 300yrds. By that I mean using either round with my rifles zeroes I can quickly hit a steel silhouette with good combat effective hits out to 300yrds. Can I go back and forth between the two and keep a bullseye hit? No, but it is still close. This is why I don't mind having the 193 as my backup/reload for the TAP.
