4000-MR burn rate

[wildchild]

Havn a tough time finding a burn rate for this powder. Im assuming its similiar to H4831?

Maybe a tad bit slower than H4831 but just ahead of H-1000.
You can find it on the burn rate chart on Ramshot's website.
Not, in my opinion, the most accurate but the only place I know 2000-MR and 4000MR are posted.

I couldn't find it on a burn rate chart either. I scoured the net looking for chrono data to compare. The data I found seemed to suggest that it ispretty close to H4831. Alliant's load data seems to indicate it to the fast side of H4831 in 30-06 and just to the slow side of H4831 in 300 win.

I have found 4000MR to be very close to Re19. Often different powder burn rate charts show different relative locations for the same powders. In my 9th edition of the Hornady manual, Power Pro 4000 MR (#124) is located just between Re19( #123) and H4831 (#125). Loads using PP 4000MR and Re19 in the .243 W (87, 105 gr) and .300 Win Mag (178 gr.) are very close.

PP 4000 MR is a very useful powder.

firewall has it correct.
Just like any other propellant, the design will respond differently in different applications, but Power Pro(TM) 4000-MR is generally in the Reloder(R) 19 (and 4831) range. It is a good bit faster than H1000, so please be careful believing those burn speed charts out there.
This powder is way under-loved, probably because our supplier refuses to allow the export of the thermochemical data to Germany (ITAR tech data), hence no Quickload input.
Shoot well,

Yes, thank you for your response, and thank you for making this powder in the U.S.
