“...if we replaced them and said well, you can only have a magazine that carries five bullets or ten bullets, isn’t it just possible that we could reduce the carnage... “
If it takes 10 minutes for the police to arrive, limiting a maniac to 5 round magazines will not make much of a difference. And that is assuming that maniacs will obey the new laws.
IIRC, the USMC Known Distance rifle qualification course required us to fire 10 rounds rapid fire from 200 yards. From a standing position we dropped to sitting, fired 5 rounds, changed magazines and fired another 5 rounds.
We did the same at 300 yards, but it was from standing to Prone, 5 rounds, change magazine, 5 more rounds.
60 second time limit.
Many of us managed 10 rounds in a 12 inch bull on both rapid fires.
Of course, we had the 10 rounds slow fire, Standing position from 200 yards, then slow fire at 300, 5 Kneeling, 5 Sitting. We finished with 10 round Prone slow fire at 500 yards.
All with iron sights.
I remember standing at the 500 yard line thinking “man that
is a loooong way away”.
