Ruger's GP-100 is an excellant choice for a general purpose handgun.

The ORIGiNAL .38 S&W Miltary & Police Special (to use the full legal name) cartridge was rolled out in the late 1890s (yes, I said EIGHTEEN nineties) and consisted of a 158 grain round nosed lead bullet driven by 21grains of BLACK POWDER. For years, 158 gr LRN was the standard .38 Special round, then along came a company called Super-Vel with a hot-chit 125 gr jacketed hollowpoint- and away we went on ammo designs.

There are .38 caliber pistol bullets as light as 95 grains, and as heavy as 200 grains. Energy = mass x velocity squared. Then things start to get complex- the ballistic co-efficent affects how the bullet flies thru the air, the sectional density effects how it acts when it hits, as does the design of the bullet.

But back to the original post- hollowpoint bullets are no louder than any other bullet- your range may restrict firing of .357 Magnum ammo, which, in general, IS louder than .38 special- especially a mild wadcutter target load.

Since the original question has been answered it should be okay to wander afield a bit.

"... sectional density. Whats real crazy is if you look at two projectiles that have the same SD and same velocity and have the same design of hollowpoint, they both get the same penetration."

Well, if you fire two identical designed bullets at the same speed, yeah, but you don't need a calculator to learn that. But, that's not what SD is all about. Sectional Density had a lot of meaning a hundred years ago, some meaning fifty years ago, but absolutely none today.

Sectional density is a simple mathmatical relationship of diameter to weight, nothing else. It includes no consideration of how the bullets are made or caliber of the bullets. You can easily find .22 cal and .35 cal bullet with equal SDs but the one with the larger mass will penatrate deeper.

During the old solid lead bullet days SD in a given caliber meant something. It even had some validity during the early "cup and core" jacketed bullet days. But, ever since bullet makers started changing jacket thickness and core hardness, SD no longer tells anything about a bullet's penatration quality. Instead, it suggests a light jacketed hollow point .224" 55 gr. thin jacketed varmint bullet will penatrate equally as deeply as a military or target 55 gr. full metal jacket and that's clearly not true.

Wow, there is some deeep knowledge going on in this thread. I LOVE my GP100, maily for its simplicity. Go to walmart & pick up a box on FMJ .38 special rounds, and then go to the range to enjoy the GP100. Worry about trying the 357 magnum rounds later; just have some fun this first trip.

And shooting is one of the most American things one can do, besides voting and barbecuing on the 4th of July!

You don't need to know anything about the physics excepts for which end goes bang and keep your finger out of the trigger until you are COMPLETELY ready for that bang.

Besides that, we're just talking about extra credit!

Thank you, everyone. I am going to the range for the first time today. I'll give a report when I get back home.

I'm leaving in a few minutes. I'm bringing my gun (), ammo, hearing protection, eye protection, paper targets all packed up in a range bag. I'm so excited.

Thank you so much for being so encouraging to me. I appreciate it.
