9mm Range ammo?

Hello,

I have been trying a variety of different loads 115grain 124grain and 147grain FMJ at the local range.

Here are my questions, what is the bbl twist rate for the 1911 DS in 4.25" bbl?
Is this the same twist rate for the 5" bbl?

If anyone knows where I could find the tech specs on the Prodigy that would be useful, I would appreciate it.

I have read that the heavier bullet has less (perceived?) recoil than the lighter bullet. Is that true?

I know that government agencies test ammunition, are any of these test published and available to read.

Personally, I have been shooting clay shotgun sports all my life and I know how important loading, components, and shot are. Not to mention powder and primer choices are to successful target shooting.

Just looking for as much info as I can get on 9mm ballistics and info that will aid in accurate target shooting. I am not going to load but would like to be able to understand what I need to look for in an viable target load.
 
According to a Guns & Ammo article the DS with 4.25 inch barrel has a 1:16 twist rate. That seems a bit slow to me but I don't know that it matters much at 25 yds and in.

I don't see much call to use heavier bullets as range ammo. 147 gr seems to me to be a specialized weight developed for sub-sonic results to still get adequate penetration. If you also carry your 9mm I suggest you practice with the same weight as your carry ammo. If it is pretty much range use only use whichever 115 or 124 grain ammo that is A- Accurate and B- Reasonably priced.

1:16 twist (per SA’s website). Both barrel lengths.

As for the rest…you’re gonna have to find what your pistol likes best. As you know from loading for shotguns—they are all individual and what works great for one may work poorly in the next.

Thanks,
The pistol seems to group the 124 gr pretty well but the slow and heavy 147 seems to make one hole (all off a rest).
So far so good, Speer seems to make the most consistent ammo but I am new to this and really need to test a lot more.

Honestly? Until you start shooting longer distances—25yds +—you really won’t see any difference between, say a 115gr FMJ and a 147gr JHP, POI wise…and when you speed up, the difference grows even smaller.

I practice with 115gr blasters and carry 147’s all the time…and 147’s tend to give better penetration than lighter bullets, as well.

Most people that I have had a chance to talk to seem to suggest the 124 gr load is best.
 
The 147 grain 9mm bullet was first introduced to be used subsonic in suppressed 9mm subguns. LE started shooting 147 grain in handguns and it is now common-some believe it penetrates better than the lighter bullet.

For the 8 years I had my firearms training business I used an average of about 21,000 rounds per year of 115 grain 9mm ball in a wide variety of of pistols. It functioned well and was accurate enough for defensive training.

For carry ammo I use Hornady Critical Duty 135 grain +p in 9mm, 220 grain in .45. I have killed large hogs in the corral pen with the .45 and the round gets the job done

As for bullet weight...On the assumption you will be using defensive ammo at some point, use the same bullet weight for range use that you be using for defensive rounds to eliminate one of the variables.

Again, this isn’t necessary, at all.

As long as you’ve confirmed reliability & accuracy with your carry loads, it doesn’t matter if you use a different weight for range vs. defensive use.

You really aren’t eliminating a variable, at all, unless you practice with the exact same load you carry…which, if you’re going to run a premium JHP, gets real expensive real quick.

Agreed. It's range ammo. Practice at defensive ranges. Unless you are shooting bullseye beyond 25 yards, bullet weight in 9mm won't make any appreciable difference. I recommend you shoot up your premium carry ammo once or twice a year in practice and replace with new. If you can find practice ammo at a good price, buy it cheap and stack it deep.

Probably true, but the difference in price is minimal. All my range ammo is 124 gr. and almost all of my HST is 124 gr. I did run a bunch of 147 though and didn't notice an appreciable difference in POI.

Top Gun Ammo is currently selling 124 and 147 HST for $30/$31 per 50 rd. box. Which is a great price and which I will be picking up some of very soon.
 
115 or 124 for range work
i would imagine 80% is and has been 115 grn.. save costs of reloading. for carry stuff its higher 124 or 147
 
I like 124 gr for range. I feel I get the best performance/accuracy from it, but that's me. As for felt recoil, I think this is really a placebo effect. As the bullet gets lighter it has more powder thus more oomph, and vice versa, so the felt recoil really evens out - according to physics,

I feel the same.
