Liberals think 30 round magazines are E-V-I-L, and 10 round magazines are much safer, less E-V-I-L and thus more tolerable because a "bad guy with a gun" has to reload more often and thus able to be captured while reloading.
Of course, when it comes to firearms, pro-gun-control advocates are talking out their ass.
In the below video, Sheriff Ken Campbell of Boone Country, Indiana has a professional competition shooter and a lady novice fire various timed drills with aimed shots. The first 2:00 is text clearly explaining the terms used.
Here are the numbers:
Pistol Drills | Professional | Novice | Rifle Drills | Professional | Novice | |
2x 15 round | 20.6 | 22.9 | 1x 20 round | 12.2 | 12.26 | |
3x 10 round | 18.0 | 25.5 | 2x 10 round | 10.7 | 14.63 | |
5x 6 round | 21.5 | 26.9 |
As you can see, the numbers are not significantly different either the total time between the shooters or the time increase to reload. The best-to-worst time spread for 30 rounds is only nine seconds, which isn't a lot of time.
For an additional reality check at 9:35 of the video a man was crouched "concealed" 25 feet away, who started running when he saw the reload taking place and stopped when the next round was fired. the guy got to within about 8-10 feet from the novice shooter, he barely made it out of concealment for the professional. Neither of these would have ended well for the other person. Also, if you notice throughout the video, the shooter's weapon is never "empty," meaning it always had a round in the chamber during reloading so the shooter could shoot anyone who attempted to intervene while they were reloading.
Before you get all excited and try to tell me about Gabby Gifford's shooter (I by policy do not mention their names) who was subdued during the reload, that happened because he basically flubbed the reload in the middle of a crowd of people, basically an arm's length away.
In closing, remember that anything that someone who is "pro-gun-control" is selling you a bill of goods. They don't want to ban all guns because they like the military, police and their private security teams to be armed, just not you.
