Load Testing: Alliant Sport Pistol powder

[tdogg]

? Alliant has no data for a 135gr anything, much less lead.

They do have load data for coated lead in 124 and 145 from Acme.  In addition, it is in a reasonable OAL length regime similar to most 9x19 CZ chambers.



I was interpolating between the 124 and 145gr ACME NLG LRN.

Oh, and I'm pretty sure I don't want to look behind the Wobbly curtain!!

Hope this helps.

Cheers,
Toby

The velocity figures for 3.5 and 3.6gr show a velocity increment of ~20fps per 0.1gr. Therefore, 3.7gr would still be shy of 1000fps, and definitely not anywhere near 1050. It's the calculation of 3.7gr being the max that I'm saying was in error, as proved by the chrono numbers. So the true Max Load for Sport Pistol with a 135gr LRN is probably closer to 3.9gr. But only more testing will tell us.

Does that answer your questions ?

I guess that means you are not going to see how it does at a bit of a +P or NATO pressures?

I have to leave something for you to do.

I have some data for the group to digest. I am switching over to SNS Cast Bullets to try and save some mollah. I tested their NEW 125gr Round Nose. This time I made sure my OAL for all rounds tested was a narrower range than when I first started testing with the PD 124 JHP. My results were higher than Alliant's data for the ACME Coated 124gr even though my OAL was slightly longer. Maybe it could have to do with the longer P-09 barrel, just a guess.

As a side note, I went shooting yesterday, not as a powder research activity, but as an enjoyment, accuracy and handgun/ammo compatibility.
Using my CZ 75 SP-01, with a 13lb (Green) recoil spring and OEM main.
Originally, I was looking to reload my 124gr Xtreme RN at 4.1gr with 1.12 OAL, but my brand new Lee Loadmaster Auto Disk wouldn't go to that exact weight, so I settled for 4.2gr, which the Loadmaster kept loading with an amazing consistency.
Anyway, my shooting with the 4.2gr was absolutely beautiful.
At 7 yards, groups were accurate and controlled pairs were very tight. Which makes me believe I have achieved  a very good combination between the Alliant SP powder and my CZ.

Thank you for taking the time to do the testing and reporting!

Saying all that, I highly doubt your life was in any huge danger, simply becasue 9mm allows +P chamber pressures and the max velocity will vary slightly between bullets. I say all this for your edification, so that your future load testing can proceed in greater safety and with more understanding.

Wobbly speaks wisdom. Side note, Alliant publishes +P load data for Sport Pistol as well.

I like this one. That's some serious pressure build up in that case.

There's an easier way to get them all on a single page.   Go to the product page and select a powder to research.    Then from that page there is a link to all load data for that powder.

I see.  You were trying to show us Alliant's load data.

This thread is about testing Sport Pistol specifically, and more precisely than simply by bullet weight.  You'll find all sorts of threads in this subforum doing extensive testing with various powders and bullets.

The very first post in this thread actually listed all of Alliant's data for Sport Pistol in 9mm, though I see Alliant has added a couple more bullets since that post last year.

When I decided to try Sport Pistol powder a few month ago, I went all out and bought an 8lb canister.
As of now, all my reloads using other powders have been long gone, so all I am shooting now is SP.
I might be wrong, but the more I shoot that powder, the more it seams like shooting Titegroup.
Powder weight wise, recoil wise and maybe even dirtiness wise.
What are your thoughts about it?

[wdfwguy]

I bought an 8lb jug as well

I've been reloading for almost a year and tried 5 or 6 powders, but this is my favorite.  Meters well, and it's been the most accurate and consistent in all of my 9mm loads.

I've been running Blue 147g RN (actual weight 149.9-150.1 for most) over Sport Pistol for quite awhile now in my SP01. For what it's worth I've been using 3.2g-3.3g (my Dillon dispenser sometimes throws .1 high) of Sport Pistol with an OAL of 1.140" using the Blue 147g RN. Mixed brass and Winchester small primers with a taper crimp of .002" (actual measurement is .378"). I get excellent accuracy with this load and it feels nice. It's my current IDPA and USPSA load and has a PF of 133ish in my gun. I know it's not the brands you specified, nor is it a FP, but I hope this helps some.

I bought some Sport Pistol to try in my .38 Spl that I shoot in ICORE. Hoping with the SNS 160 gr bullets the gun will stay a little cleaner and my reloads will be faster with clean cylinders, but we will have to see about that.

Today I decided to test some RMR 124 JHP with the powder. I shot two 10 shot groups over the chrony. 10' and 85 degrees.

4.0 grns Alliant Sport Pistol, RMR 124 JHP, 1.06 OAL . Alliant lists 4.4 as max!

 Fed and functioned perfectly in CZ P-07 and Glock 19.
Short fat RMR JHP made me lower my normal JHP OAL but they functioned good and I am happy.

CZ P-07  Average was 1055 for a PF of 130

SD was 10 and ES was 24.

Seemed to be accurate and recoil was mild. I am out of coated 9mm at the moment but I am anxious to see if the SP does cut down on the smoke. Coated bullets smoke way less than lead but early and late in the day or at a night shoot the smoke can be a distraction.

Rather than starting a new thread, is the consensus still the same on Alliant Sport Pistol? I am almost out of N320 and given the volume that I shoot and the shortage of 4lb jugs of N320, I am open to trying out ASP, assuming it's as good as previously praised.

I reload for a 2011 .40S&W and 9mm for my CZs.
