Is hollow point ammunition any noiser than any other ammunition?

    I am very new to guns and the range I'll be going to does not allow hollow point cartridges for target shooting. They said "because of the noise". Is hollow point ammunition any noiser than any other ammunition? Also, I bought some .357 magnum 158 grain loads. When I got them home I saw they were hollow points. I know this is probably a dumb question but are there .357 magnum loads that are NOT hollow points? If so, can you tell me what brands or what I should ask for at the gun shop? Thank you. :eek:

    I saw some .357 non-hollow points yesterday online, but why not just use .38 special for targets? You can find the .38 special in FMJ easily at the Walmart i visit. I think the .38 is a bit less expensive, as well as easier on the ears & wrist.

    This is what i saw yesterday & this is a new site vendor. Heck, i'm kinda tempted here, myself.

    Never heard of that before. I don't know why cartridges with hollow point bullets would be louder than with solid points. I'd call the range and ask for clarification on this.

    The .357 Magnum is louder than the .38 Special because it's more powerful. Both cartridges can use the same .357 inch bullets, and there are .357 Mag rounds that are not hollow points. Yes, ask at the gun shop, I'd think they ought to have a box or two.

    Well, I am going to use the .38's for target shooting but I want to be familiar with shooting the .357 magnum, too. I want to experience the recoil so I know what to expect. I just want to really know my gun and experience shooting it in both calibers.

    So, most .357 magnum cartidges are hollow point, I take it. How do you know by looking at the box whether it's hollow point or not. I looked the box over very closely after I got it home and discovered the .357 magnums I bought were hollow point and I don't see where it says that anywhere on the box. Or is that something that most shooters know?

    I have to read the box. If you need to, ask to open the box to see one. Some places might be offended, but i've never had that problem. The last time i was at Walmart, there was a city policeman comparing two different rounds, side-by-side.

    Alternatively, you could ask the salesperson for help with it (not so much at Wmart) or look for popular brands online with the features you want then ask for that brand.

    edit* What brand is the .357 ammo you have?


    I'm kinda surprised they have a ban on HP's at the range; i would think shooting HP would be safer, ricochet-wise. I've never noticed the noise difference personally.

    The Magnificent .357 Magnum

    I'll bet somewhere on that box of cartridges you bought are the letters HP (hollow point) or maybe JHP (jacketed hollow point).

    Sounds like you need to look for FMJ on the box... Full Metal Jacket... They're actually more common to find in my area than HP's.

    I'll look again. I would never think to just look for "HP" or "JHP". I wouldn't know what that meant if I saw it, but I will now. Thank you. I am very new to all this and as you can see, I have a lot to learn. :eek:

    Look for ammunition marked FMJ. FMJ = Full Metal Jacket


    oops, beat me to it.

    HP ammo is not louder. The more common NON hollowpoint .357 mag will be JSP (jacketed soft point) and SWC (semi-wadcutter) You may also find some TMJ (total metal jacket) which is used to reduce lead vapor in the air- jacket metal wraps all the way around the lead core, including the base. Some ranges have restrictions on the use of partially jacketed bullets since the jacket metal can come loose on hitting a hard backstop, and bounces around a bit. You may also find RN or LRN (lead round nosed).

    Before buying more ammo, you may want to check with the range and see exactly what their requirements are- see the line below.

    Yes, I looked and it says ".357 magnum 158 gr. JHP" I didn't know what "JHP" meant, but I do now. Thank you!

    Also, thank you to you, too. I will look for FMJ. I am guessing Full Metal Jacket's are not hollow point, then.

    Thank you, everyone, for all your help.

    Lets make some noise!!!!!!!

    Next time go there with either a 44 mag or .454 and see what he says about the noise. I thought people wore hearing protection ?

    FMJ or as the military calls them, Ball ammo are what you need to look for.

    Winds, since you didn't know about the JHP thing, you might have missed the 158 gr. thing. That means 158 grains, which is a measure of mass for the bullet, the actual projectile.

    .38 special bullets are often 110 grains, sometimes as big as 135 grains. This is one reason why the .357 magnum ends up having more energy at impact, since the bullet has up to 40% more mass.

    I am no ammunition expert, though, just a math guy.

    Thanks, Chris. I did know the higher grain the more velocity. Actually, the .38 specials and the .357 magnums I got are both 158 grains. But thanks for the info. I am learning and can use all the help I can get. I've had this gun for about 3 weeks now and I haven't shot one round out of it yet. I'm working up to it. :eek:

    Oh, geeze. Thanks for correcting me. See why I haven't taken my gun to the range yet? I'm afraid I don't know enough!!!!

    "Is hollow point ammunition any noiser than any other ammunition?"

    No.


    ".. are there .357 magnum loads that are NOT hollow points?"

    Yes.


    Your choice of a .357 is one of the best, not withstanding the current lack of recognition by the press and people hyped on currently popular large capacity but puny handguns/cartridges.

    Have no fear, you can be assured that all factory ammo is quite safe for any firearm in good condition. After you put a half box of ammo through it you will be laffing at yourself! ;)

    Winds, one of the best things about this forum is that there are a huge number of great experts on so many subjects, and they are always so willing to help people out who ask sincere questions.

    There are also people wiser than I who would leave this alone so someone more knowledgeable would address it.

    I am NOT one of those experts, but I am going to take a quick stab at this one and someone will fix my errors.


    The mass of the bullet does change its velocity. Given the same pressures in the casing at the time of firing, the heavier the bullet the SLOWER it flies. So people make a choice: smaller/faster or bigger/slower.

    One can change this equation by increasing the pressures in the casing so the same mass of bullet can be shot at faster speeds, thereby increasing its energy at impact. .38spl +p adds this extra pressure, allowing the shooter to choose a larger-massed bullet that will fire at the same speed as a smaller-massed bullet in a standard pressure round.

    Some people choose a large bullet (you said you had a 158 grain .38spl round which I'd never seen before) even though they know it will be going slower. And some choose smaller bullets (110 gr.) so that it will be flying much faster.

    The .357 round is loaded to even higher pressure than .38spl +p and thus can fire even larger bullets at the same speed and even higher speeds, giving it so much more energy at impact.

    Now, larger in mass does NOT mean it creates any larger hole, since the larger mass in the same caliber necessarily means longer, not wider. Here's where my knowledge gets really murky. I've gathered that more energy means a larger hole at the very instant of impact (temporary cavity), but the same hole as any other bullet of that caliber of any speed (permanent cavity). And this is the reason why .40S&W and .45acp are so useful: the hole they make is so much larger.

    That was fun.

    Thank you ever so much for that vote of confidence. You give me the encouragement I need. I will bring my gun to the range Tuesday and report back to you. I hope I'm laughing at myself and not discouraged.

    You're probably wondering why I even got a gun in the first place. I was seeing this guy who took me shooting and I got hooked. I wanted my own gun and he suggested this Ruger GP100 for a variety of reasons. Now that I have the gun, he has since broken up with me and I kind of lost my "mentor" but I'd still like to keep the gun so I am trying to learn on my own.
