The Sierra #2121 (125 gr) bullet was specially designed for the 300 BLK. The Speer 125 gr tnt (although one of my favorites) is not ideally suited for the 300 BLK in general.

Yeah, it just sits there on the shelf because no one knows anything about it much. I was gonna buy a few more pounds for myself as it seems 296 and 110 are hard to find right now.20X11 wrote:Is this guy selling any of it?rebel wrote:I know a guy that has some- a lot of it

Re: Alliant 300-MP load data from Alliant
This is super helpful as I'm going to be using 300 MP to reload some 300 blackout with 100 grain bullets. Thanks for posting!!!danner wrote: ↑Thu Apr 09, 2015 7:19 pm I don't have any 300-MP but looked into it and would like to if I can find any. Alliant didn't have any load data for the 300blk so I emailed them about it. A couple of days later I received a reply and thought I would share the response. Maybe this will help someone.
My info has been removed, but the remainder of the email is exactly as received. No barrel length/twist was listed.

I have shot a fair amount of 300-MP with 110's and 125's, along with a few different 150's. Performs similarly to H110 without the pressure spikes at the top end. Great accuracy with the lighter bullets. Have fun, be safe...BTW, their data is GTG.

I have been using 300mp for several years and can’t recommend it enough for light weight, 110-130gr, supers.

Yup agreed. I like this powder allot too!
Just worked up some Loads around the Hornady 135 FTX bullet with VERY VERY good accuracy. Ended up lil north of suggested maximums. . Couldn’t chrono too much rain and wind. But single hole accuracy from my RARR!
