Difference in ammo grain counts

[legi0n]

Usually, the 147gr bullet in 9mm has a muzzle velocity of 990fps (Rem, Win, S&B).
Yet Buffalo Bore advertises a 147gr 9mm round that exits the muzzle at 1200fps.
Clearly the recoil of the latter will be higher.
There may be other supersonic 147gr rounds that I don't know of

Maybe self defense is irrelevant to you( I guess you are the type to just lie down and take it), but if I choose to unlock the gun safe beside my bed every night and "other" necessary steps to be prepared(and I'm not saying I do), that's my choice.

Now we are talking about that which must not be spoken of. I believe CRAZYLOCH is speaking tongue in cheek.

Does the grain count effect how dirty the gun gets ? For example is the 115 "cleaner" than the 124 or 147 ?

Not really. The amount of residue you are left with in the barrel depends on the primer, type of powder and amount of powder used. All else being equal, rare event, then with the same primers and type of powder the 147 gr loads (assuming there are handloads so you know the other two are indeed equal) will leave less residue because you will use less powder. Factory ammo is a crap shoot.

Regardless of how dirty the powder is, one SHOULD always clean before storage

Boy you must be a noob, just a kid, or just plain ignorant.

In Canada using a restricted firearm to defend yourself will likely get you landed with involuntary manslaughter. It is a restricted firearm, and ONLY to be fired at a designated range or venue authorized to do so.

If a threat was to cause bodily harm to you or your members of my family, thats why we have better and Non -restricted choices like a Shotgun locked with easy code access at the ready. Now i am not saying that, it does not mean you still won't be charged by the Crown for manslaughter if YOU cause grevious bodily harm to anyone. But it is one less thing to explain to the crown or the constables when they show up.

my 2 cents

Heavier bullet will require either smaller powder charge or/and slower burning powder. So, in the end you get 'smaller blast' or/and 'slooower blast' resulting in less felt = not as snappy recoil.
Accuracy with subsonic velocities is better due to not having to break sound barrier that 'wobbles' bullet. Ideally, barrel twist rate should 'match' bullet weight and velocity for best accuracy too.

This is a widely held misconception that subsonic bullets are inherently more accurate than supersonic. The bullet breaks the sound barrier in the barrel, once it exits it only slows down, so the maximum velocity is at the muzzle. What indeed induces loss of accuracy is the transition from supersonic to subsonic. In fact, the "effective range" in snipping rounds is defined by the distance they go subsonic because of such loss of accuracy. For pistols, it's simply much easier to keep it subsonic all the way in the short distances involved and avoid the problem altogether. Olympic .22 lr competition ammo is always subsonic for that exact reason.

Just got back from the range and for what it's worth the 115 "felt" the best to me so far as recoil. No cycling problems with any of them.

Very happy with my decision to go with the SR9.

 

[st1264]

I've heard good things about the SR9. Inexpensive and well made.

No, I am not a noob,kid or ignorant....I just know what my PRIORITIES are...unlike you. My FIRST PRIORITY is the defense of my family, whether I go to jail for that in this ridiculous country is something I will deal with after I have protected my family. A man thinks about the well-being of his family before his own. Furthermore, JHP can be used in certain non-restricted firearms as well as pistols and revolvers...which was my main point to your suggestion that JHPs were useless in Canada...which of course they are not, whether they are used in non-restricted or restricted firearms.

bit of a thread hijack?

noob, enjoy your ruger! they are a hoot to shoot, i should find one to add to the colection. (don't tell my wife!). Personally i prefer 115 in all my 9's, but will use 124 in a pinch. I hate the 147, if i want a heavy bullet moving slow i'll shoot 38 special or 45, both of which i prefer the feel of to 9 in 147gn bullet weights. But as stated, it's all personal and gun preference. Have fun, shoot well!

 

[COREY]

I have had good luck with the 147's in my Shadow and my 92F. The guys at the range find that thier best accuracy is usually with 147's over 124's. That being said, I had a Hornady 124 FMJ load that worked quite well too.

 

[cyclone]

Noob. The correct way to ask the question is "Which bullet weight is best?"

This is a good question for a noob to ask.
