That's some impressive shooting. I'm guessing a lot of it has to do with your skill more so than the bullet.
I fail to see how this is any endorsement for the 10mm round, but for an accurate firearm? Would not any handgun capable of shooting tight groups do the same thing? Might not bang the gong as loud as 10mm would though. :grin:
While it's cool and impressive that you can use a hand gun to hit targets at that range I guess the question in my mind would be, why not just use a rifle?
^^ The assumption is you don't *have* a rifle. As was the case in the example I cited, which was cops using their duty handgun to fight bad guys at longer ranges.
For personal defense, you are correct in that it would be unlikely that you would be engaging anything at that kind of range, and shooting a fleeing person will get you in trouble.
BUT what if the zombies come, and you aren't near a rifle? Do you really want to wait til their 7 yards or less away to open fire? I sure don't!!!
Everyone knows that you could build a rifle from scratch before a zombie got close enough to you if you saw it at that kind of range.
So Kolat, how often do you shoot at MIca? We went down there a few times last year but did not got his year.
Faster = less wind drift, and less bullet drop, and more retained energy when it gets there.
Took me a while but this is what I come up with for various autoloader cartridges for bullet drop out to 500 yards.
9mm, 147 grain RN FMJ bullet, 1000 fps, BC of .208 according to speer's web page.
zeroed at 25 yards
100 -11.14
200 -62.54
300 -161.61
400 -315.27
500 -530.41
.40 S&W 180 grain bullet, 1000fps, .164 BC, used the hornady since the speer was a different profile bullet.
zeroed at 25 yards
100 -11.36
200 -64.76
300 -169.29
400 -334.10
500 -568.86
10mm, same 180 grain bullet as the .40, 1350fps, .164bc
zeroed at 25 yards
100 -4.15
200 -35.49
300 -103.63
400 -216.10
500 -380.84
.45ACP, 230 grain RN FMJ, BC of .153, 850fps
zeroed at 25 yards.
100 -14.88
200 -86.13
300 -225.01
400 -444.65
500 -757.48
So the 10mm requires almost 200 inches less compensation at 500 yards than the comperable .40, and has almost exactly HALF the drop of .45 at that range.
As for comparable energy at that range.
9mm : 161 ft-lb
.40 :168 ft-lb
10mm : 216 ft-lb
.45ACP : 160ft-lb
I'm actually kinda surprised to see the .45 coming in dead last for energy at range also.
