What Does It Weigh?

It's Pinewood Derby time at the Casa del G. That means the scale has been dragged out of storage and set up for the duration. It got me to thinking (always a dangerous proposition) about what certain gunnie items weigh, when a thunderclap hit me: What do the various magazines we use weigh?

So I reached into the box 'o' magazines, loaded up a representative sample, and sat down with camera and scale. Here are the weights of several popular magazines and loaders out there.



Let's start out with one of the age-old rivalries: AK vs. AR

AR-15 30 round magazine

AK-47 30 round magazine

Hmmm. The AR-15 magazine weighs 17.4 ounces, whereas the AK mag is significantly heavier at 28.2 ounces. Guess that's the difference between a poodleshooter and a .30-30...


Next up is another rivalry: Glock vs. 1911, and .45 ACP vs 9mm

Glock .45 ACP 10-round magazine

1911 .45 ACP 8-round magazine

SigSauer P226 9mm 15-round magazine

The Glock 10 round magazine is a lot heavier than the 1911 magazine, and with only two more rounds capacity. The 10 round Glock mag is even heavier than the 15 round Sig 9mm mag, so you get 5 more rounds with 0.4 ounces less weight...



Lastly, here are two popular revolver reloads.

HKS Speedloader #36 5-round .38 Special

Bianchi speed strip 6-round .38 Special

Not much difference here, really, given that the speedstrip has an additional round.


Lastly, because I'm the curious type and figured y'all might be interested, I weighed single round of each. .22LR weighs 0.2 ounces a round; .38 Special JHP, 9mm FMJ, and .223 FMJ all weigh 0.5 ounces each; 7.62X39mm weighs 0.6 ounces; and the surprise heavyweight was the .45 ACP, coming in at a hefty 0.8 ounces! Thus concludes our weigh-in, where we answer the age-old question, "How the hell much weight am I lugging around after all?"

While I have the scale out, anything else y'all would like to see weighed?

That is all.

How about weighing the odds on when the Commonwealth of Massachusetts actually seats Senator Scott Brown?

How about some 12 Gauge rounds?

Jay,

How about 7.92mm mauser vs. 7.62x54 Russian vs. .303 enfield vs. .30-06 M2 ball vs. 7.7 Jap arisaka

or some variation on the standard infantry rifles of ww2.

How about same Glock vs 1911 vs Sig - the whole pistols, not just the mags?

Brad's idea of WWII rounds comparison sounds pretty interesting too. I would add 7.92x33 and 7.62x39 to the mix - while they were not among the main rounds of the war, they did see some limited use towards the end.

Obsession is not good.

Starik,

Glock vs. 1911 has been done... :)

Starik,

Thanks . . . I'm a fan to beat the band of the M1 Garand, hence the idea. Maybe we could even toss into the mix the French 8mm Lebel and/or the Italian 6.5 Carcano.

As for the shorty rounds, I'd say do the following:
7.92x33 vs. 7.62x39 vs. 5.56x45 vs. the new 6.8spc vs. the new 6.5 Grendell. Just sayin'.


Jay, as for your surprise on the overall mass of the venerable .45acp, I did some math. One ounce is about 437 grains. Eight tenths of an ounce is roughly 349 grains for the total cartridge mass. Subtract out the 230 grains for the bullet, and you're left with only 119 grains for the case, primer and propellant. I'm not really surprised by this one.
