I have no set loading pattern for any of my firearms with the exception of defensive firearms. Those get full handgun cylinders, or full magazines +one chambered, and 28 rounds are in my AR-15 magazines.
Hunting, the gun is loaded to legal capacity.
When I shot SASS I loaded 5 in my .45 Colt revolvers because the rules limited us to 5. I loaded with two in my old SxS shotgun, but some stages allowed those with an 1897 to hold more). Rifles were loaded per stage rules.
When I’m training for a handgun target or plate match I load to capacity for the individual stages I’m practicing for.
When I’m solo or with other shooters testing or plinking, it just doesn’t matter to me:
When I’m shooting the gun (or mag) may be full, may be half full, may only have one, may have a mix of live and dummies, etc. depending on why I’m shooting that particular load or firearm.
Stay safe.
