147gr. 9mm ammo

what gun is it?

147gr has the same pressure (35,000 psi) as both 124gr and 115gr, so you have nothing to worry about there. You'll have to consult the owner's manual to find if your gun can shoot +P and/or +P+.

Hope that helps.

As cc said what gun are we talking about?

Standard pressure ammo should work fine.

I am not a fan of +P or +P+. If you need more velocity or power get more gun.

147 GR should not be a problem as others have pointed out unless labelled differently it is standard pressure ammo.

As far as +p of any vintage I think a reasonable amount is fine through most pistols. It can be debated if it is needed but most guns can take a reasonable amoungt.

I shoot 124gr +P gold dots out of my 1972 BHP without any issue. Some people will tell you a non-MKIII BHP will turn to dust in your hand if you shoot +p ammo out of it but my experience shows me this not to be the case.

I am not sending 1000 rounds a range session down the pipe but a few thousand over its lifetime is not going to turn it to dust IMHO.

I switched to Win. SXT 147gr. instead of 124gr Speer GD. Less percieved recoil and highly accurate in my "bought new in 2000" non-rail P226.

I have been running more and more of the 147s too. I actually like them out of the smaller shorter barrelled 9mms. My Kahr CW9 eats them up.

Why? Why should I switch calibers because I don't like the ultraconservative, underpowered standards set by SAAMI? NATO ammunition is anywhere from 4% to 12% higher than SAAMI, in comparison.

A well made, modern firearm such as my HK P30 will have no issue with +P ammunition. It's only a 10% increase in pressure, which is hardly anything to write home about. (35,000 to 38,500 psi and the 9mm can handle up to 44,000 psi)

IMO, non +P 9mm ammo is underpowered. The reason we started adding pressure to the 9mm was to increase terminal ballistic performance from the original standard set in 1902. (Which it did!)

When shooting 147gr 9mm, there is no reason not to use +P, as 147gr was intentionally made to be "soft shooting." My practice ammunition(s) (115gr Federal Champion or my 124gr NATO Winchester Ranger) shoots hotter than than my Federal Tactical HST 147gr +P carry ammunition. (NATO pressure is, with rare exceptions, lower than +P).

I say the above as I tested both the 147gr standard HST and 147gr +P HST at the range in depth; I fired 150 rounds of both to test for differences in accuracy, follow up shots and recoil, and the differences would have to be measured microscopically, as I couldn't discern any.

You can send it to me, I'll run it through a Glock and won't think twice about it

147gr HSTs are all I shoot through my 9mm Sig P239, other than some occasional range stuff.

LOL to each their own. There is no end all be all round there is no end all be all gun...

I didn't say there was...? I'm simply responding to GRIZ22's incredulous statement.

Nothing incredulous about it. It is an opinion which differs from yours...

There are lots of reasons not to use +P ammo.

And, there are lots of reasons to use +P ammo. I don't get where you are going this other than just arguing opinion with opinion which is apparently what you are attempting to scold me for. He said +P has no use to him, I said it has use to me...

Yes, my opinion differs from his as it apparently also differs from yours. I still don't understand your original response to my first response. I did nothing to suggest that the 9mm is the "end all, be all" round as it's nowhere near it. I offered a fact based opinion as to why I prefer plus pressure ammunition in 9mm.

Edit: And yes, "incredulous" was a very poor choice of word on reflection.

I think its your tone in the first post which is backed up with the use of incredulous in your next one.

If you simply stating and opinion... I do not think that word incredulous means what you think it means.

Incredulous: unwilling to admit or accept what is offered as true

Honestly the difference between 9mm 115gr vs 115gr +p or 124gr + 124gr +p or 147gr vs 147gr +p is moot. They all at times get the job done and at different times they fail.

Today's modern hollow point designs are so similar its 6 of 1 half dozen of the other.

I agree. I shoot both +p and non +P defensive ammo. I personally buy what feeds and what is cheapest within reason.

Yes, yes I said incredulous was a poor choice already ; I'm doing about six things at once at the moment. It seems I need to use smilies more often, as people always assume I'm ticked off on forums for whatever reason!

As for the differences between modern hollowpoints: there are still some differences in them, as Dr. Roberts has not vetted a single 115gr 9mm round, with the exception the Barnes copper bullet, since they began vetting rounds in terms of ballistic performance. But I'll agree with you that they will all likely get the job done, and failure is highly unlikely.

As someone who hasn't fired 9mm but is planning to in the near future, I'm curious about people saying the 147gr loading is "soft shooting." Assuming both rounds are loaded to the same pressure, wouldn't the heavier bullet have more recoil due to inertia?

no. recoil is a combination of bullet weight and speed. the 147gn bullets will be going slower than the 124s. multiply bullet weight (grains) times velocity (fps) to get an idea of comparable recoil of the two loads.

They travel slower because the heavy bullet had more inertial resistance before it left the barrel though. Since recoil is an equal and opposite force, it doesn't seem that recoil should be any less if the force required to move the bullet is the same (e.g. loaded to the same pressure). This is the same reason .45 ACP doesn't recoil less than 9mm even though the 9mm has a higher velocity. Maybe I'm wrong, but it doesn't seem to make any sense that the 147gr would recoil less.

It's not that either load has more or less recoil; recoil is the wrong word, imo. It's more like comparing the snap of the .40 to the slow push of the .45; the 115gr and 124gr loads are "snappier" than the 147gr, which is why it's considered a "soft shooter."

When I say "snappier" you have to remember that it's still a 9mm, and the differences are very subtle, but they are there.

I hope that helps.

The gun would be a '70's HP. I've had several 9mm pistols throughout the years but I've never used +P or 147gr. rounds. I might just give it a try?

While I can't (and won't! ) tell you your gun can fire +P rounds as I don't know, I do know that any 9mm gun that can fire 115gr and 124gr can fire 147gr as they are loaded to the same pressure.

force is equal to the mass (weight of the bullet) times the acceleration of the bullet. force involves speed and weight. that's why i gave you the simplistic formula to figure relative recoil between two loads (in the same gun, of course).

After my comment in post #6, I should follow up by saying Im unclear on the expansion of this 147gr. SXT ammo. Im sure the GD ammo is much better in that regard, for me the softer shooting SXT is a greater advantage.
