Well you actually hunt instead of theorizing about 40 degree shoulders<<< and one more round>>> of magazine capacity....
Yrs. ago I 'used to' be concerned about ONLY 3 rounds in the magazine so, I'd also load hot + 3 = 4 total rounds.
After a few yrs of hunting "LIMITED" like that
I realized that I had NEVER shot 4Xs at game. So I quit thinking about it.
When (IF) you ever hunted a #1 there is NO magazine.
