I'm shooting 20 grains over a 110 V-max for 2150 fps in my 9" AR. Great powder.

Anyone have any QuickLoad data for an idea of where these are in pressure?

I saw this at my local gun shop and am very interested.

My version of Quickload (3.6) doesn't have this powder yet. I've contacted Alliant to see if they have the data necessary to create a custom powder file but have not yet heard back.

I contacted them last night and got this email today...

I received this email on 28 August when contacting them about load data:

At this point we have no plans to shoot the 300 Blackout. Thanks for your note.

The email regarding powder properties was sent to a Product Manager at Alliant.

RD, Did you have any pressure sign with any of the loads? Flattened primers, anything?

From what I can find from my online research this powder shows promise in getting some good velocity as it's just a hair slower than Lil Gun according to
www.castpics.net/LoadData/BurnRates.pdf

I'm running a 16", 1:7, carbine gas and am focused on supersonic loads and I saw this powder at my local gun shop hoping it will fill the bill with 110 - 150 grain pills.

I hope to get some load development data posted up here soon.
