Default Tried out some Alliant "Sport Pistol", and tooks some chrono data

Hi guys, Alliant "Sport Pistol" was available at PV so I picked some up. It claims to work well with coated bullets and load "similar to VV N320"

There isn't much load data, so I thought I'd share some chrony info here.
Standard caveats/disclaimers apply.

I am shooting 9mm 135 gn round nose Bear Creek Moly coated bullets. There is no load data for this, so I took the published 115, 124 and 147 FMJ data and extrapolated (you know y-y1 = m (x-x1) where m = (y1-y2)/(x1-x2) LOL!)
a load for 135 (even though fmj is not equal to moly coated lead). Then took of 10% for starting load.
Now as a further wrench in the works, I load my rounds short at 1.090 because my PPQ and CZ do have very short and/or stepped chambers.

Anyway, some data over 16 rounds each (I dunno how it worked out that way), using a Magnetospeed chronograph

I calculated that 3.7 would be a theoretical max, so, subtracting 10% gave me 3.3 gn. I did not notice any obvious "pressure signs" and the speeds and power factors I got back showed that my loading was pretty reasonable.

9mm 135gn round nose "Bear Creek Moly" bullets with Alliant Sport Pistol powder, loaded at OAL of 1.090"


3.3 gn
min 940 fps
max 960
avg 949
sd(standard deviation) = 6
ES(extreme spread, ie max-min) = 20

Average power factor = 128

3.5 gn
min 972
max 1001
avg 985
sd = 8
es = 29

Average power factor = 132


NOTE: I FELT that the 3.5 gn load was more accurate, but I wasn't really trying too hard.

Given that 3.3 gives a power factor of 128 and 3.5 gives a power factor of 132, then I would easily estimate 3.4 giving a pf of 130.

Now, in the bigger scheme, it probably makes too little difference for USPSA style competition and you might as well save a few grains and load 3.3 for 128 pf I guess. I mean, I probably spill more powder that I'd save for .2 grains/round.
Next time out I'll focus to see if there is any difference in accuracy, but I doubt that my skill level will allow me to notice.

If you do your own testing of this powder, please let me know what you think! So far I think it's pretty good! My standard 9mm powder is win231, but since I bought this stuff I'll use it. Might load .40 with it as well to try it.

Lead, How does the 3.5gn ASP load compare with your best W231 load? A bit hotter and requiring a bit less powder for the same PF??

Will check when I get back from vacation. Load is almost the same for 231. I will do a side by side to see if I can tell if there is any "felt recoil" difference.
I load the same bullets to the same OAL with a different 231 charge.
I'm no pro so I might not tell the difference (in which case, why not just get whatever is cheaper! LOL!) but it claims to be cleaner with coated bullets and some other marketting stuff.

I saw that Alliant came out with a new powder and came here to find out if anyone used it.

What is so special about this powder?

They already have BE-86 and Power Pistol.
