Update: I got an email from Powder Valley that package has shipped via FedEx with delivery date of Wednesday, 5/24. I will do that but in a different thread to not hijack this one.
Yes we have this Alliant Sport Pistol in 1 and 8 pound containers! www.powdervalleyinc.com Here I have attached some load data Alliant sent us that you can view! https://docs.google.com/document/d/1ELNOy2dsRIcYXooLztTMQT0ZmzVsq-AkUWejZgDugfA/edit Thanks, Powder Valley
Thank you. Alliant Sport Pistol load data looks curiously similar to W231/HP-38. Definitely looking forward to comparison range tests. As soon as Powder Valley shipment arrives today, I will put some Alliant Sport Pistol with powder coated bullets and use W231/HP-38 as control. I could also test Bullseye. Any suggestion for other powders to do contact test with powder coated bullets?
I can do some low light muzzle flash comparison test with Alliant Sport Pistol and BE-86 like I did for moderator taliv - https://www.thehighroad.org/index.php?threads/need-low-flash-9mm-powder.809859/page-2#post-10357740 Update: Package arrived from Powder Valley and I got to take some comparison pictures Alliant Bullseye (Left), Winchester 231/Hodgdon HP-38 (Center), Alliant Sport Pistol (Right) I was anticipating Alliant Sport Pistol powder formulation to be like BE-86/Power Pistol/Bullseye - small flakes. But to my surprise, it was small granules like Vihtavuori N320/Vectan Ba 9.5, extruded cut powder but cut very short as disks. As you can see from the close up comparison picture, Sport Pistol granules are same diameter disks with slightly varying thickness that is smaller than W231/HP-38 in size and thicker than Bullseye flakes. (FYI, W231/HP-38 are coated ball powder that have been flattened) Will load up some RMR 115/124 gr FMJ bullets and do some comparison chrono, pistol and carbine testing soon.
IMR Target is small thin flake powder (picture in link) - https://www.thehighroad.org/index.p...-and-vectan-ba-9-5-ba-9.817796/#post-10490012
Guys, attached are some updated data for Sport Pistol with more bullets. Good luck with our new powder. Paul
Paul, thank you for the updated load data as I am working on initial 9mm 115/124 gr and 45ACP 200/230 gr FMJ/plated/lead bullet loads.
Paul from Alliant/Vista Outdoor can better answer but the new product sheet stated "medium fast burning" - https://www.thehighroad.org/index.p...ing_alliantpowder_sportpistol_fnl-pdf.228712/ Based on the start/max powder charges, my guess is around Green Dot and Unique, likely slightly slower than W231/HP-38. Since 9mm powder charges are so similar, I am planning to comparison test Sport Pistol with W231/HP-38.
Has anyone run Sport Pistol through a Lee Autodisk? I would like to know what the throw weight is for the smallest (.30) disk in order to determine if i can throw a charge small enough for 380acp without having to use the Lee adjustable charge bar.
The .30 disk hole in my Pro Auto Disk dropped 10 charges of Sport Pistol from 2.90 gr to 2.94 gr weighed on the Gemini-20 digital scale with most of charges being 2.92 and 2.94 gr. That is VERY consistent powder charge variance! If you need to drop smaller charges than 2.9 gr, you can use this $1 mod - https://www.thehighroad.org/index.php?threads/working-diy-micro-auto-disk.741988/
Wow, that is terrific metering consistency. I'll have to keep an eye out for it at my local reloading store.
Walkalong, I doubt you will find Sport Pistol on any burn rate charts. As a point of reference, I had described this product as an accurate metering, small diameter version of American Select(R), which has been a favorite of mine in light centerfire pistol target type applications for years. (It doesn't meter all that well though.) This powder is absolutely not American Select though, so make no mistake about that. The chemistry and geometry are different, but I just used that as an example that made sense to me. The third slide of the attached file shows how the P/V characteristics of Sport Pistol are essentially the same as N320, and close to Win231 and Titegroup in these applications. That is by design, as those three powders dominate the handloading by USPSA and IDPA shooters (according to our intel). We have received great feedback from our beta testers, so I think we hit our target. (Disclaimer: the P/V chart does not show charge weights shot for the data, so please do not assume that the powders are the same because their P/V characteristics are similar. Titegroup, for example is a high nitroglycerine powder, so it's charges are materially less due to the high energy. Use only the manufacturer's data please.) Thanks for the interest in our new product. Paul
Very interesting, as I like both American Select and especially N320. I would assume that sooner or later it will get on the burn rate charts, but that info is very helpful. Thanks
Alliant Reloading (Paul) How long or what criteria is needed to put a powder on a relative burn rate chart.?? For example Bullseye 86? It has been available for a while. "(Disclaimer: the P/V chart does not show charge weights shot for the data, so please do not assume that the powders are the same because their P/V characteristics are similar. Titegroup, for example is a high nitroglycerine powder, so it's charges are materially less due to the high energy. Use only the manufacturer's data please.)" Also, in your PDF Presentation, the expelled residue "graph" Does not show the charge weight (which you indicated) so how can "clean burning" be determined.? Are these start loads, mid loads, max loads?? A powder such as HP38/W231 is indeed "sooty at low charge weights
Rule3, The residue tests were performed with all samples assessed to approximately the same velocity for a minor PF load (around 1050fps, IIRC). The pressures were obviously not all identical, but they were not low at 29-31Kpsi in most cases. I think AA#2 was a little higher. I'm not sure I know the answer to your question on burn rate charts. Shoot well, Paul
