With Magpro having a similar burn rate to H1000, I wondered if anyone had tried it with any success in a RUM?
Magpro in a RUM?

Not in a rum but I tried it in my 6.5 x 284 Norma. It is a spherical powder and pressured up quickly.
Thanks.
I was liking the spherical aspect but not if it has pressure issues.
Anyone else?

No pressure issues in a prc, running max loads with very minimal primer flattening. I'm still working on load development but it's looking really promising
Here is their load data guide, look to page 77 for RUM data...
It was not in RUM, but I used it on .338 Thor (.338 NMI) 91.5g 250 Hornady BTHP (fireforming) and .300 WSM 67.9g 215 Berger. As with anything else, YMMV.
I did not have pressure issues, as you described.

Magpro was designed for short mags and is one of the best in a 270 WSM. It is a little fast in a 300 RUM. Best with lighter bullet weights. Might work very well with hammers. That being said, the slower Ramshot Magnum is excellent in a 300 RUM. I use it when I cannot get Retumbo, which is IMO the best powder in most cases for a RUM Q

not a fan of that powder...
This is why I have some. I like it in the Short Mag.
What issues did you have, and what cartridge?
It maybe so, but it is clearly being used effectively on non-short mag cartridges.
I forgot, I also use it on my .257 WBY and 145 Black Hole bullets.

I was going to get some as my LGS had lots of it in stock but after looking over charts with burn rates and temperature stability rates, I found magpro was not very good with temperature stability actually one of the worst so I scrapped that idea quick

i had run it for a bit but dropped it as there are better choices out there. also from what i remember it was a bit faster than h1000 closer to rl25. i think i still have 5lbs in the stash tho lmao. ramshot magnum i prefer over h1000 in the rum if im going to run lighter pills and for heavies i like n570, lrt, retumbo.

What do you consider light for the rum
