What powder for 300 RUM?

[robbor]

I need to buy some powder for my 300 rum, what do you recomend?
Probably going to shoot 180s

Three top powder choices for the 300RUM:
Retumbo
Retumbo
Retumbo

Others may work, but Retumbo is THE powder for the Ultramags in my opinion.
I'm even using it tomorrow in my 6.5X384 and .264 Win Mag. It excels with heavy bullets.

Retumbo, in my .300 RUM with 180 Nosler B.T. is the cat's meow.

i've had great luck with 92 gr of RL 25 under 185 vlds in my RUM. i do think it's a little more temp sensitive then the retumbo may be.

i would like to try loads with retumbo and H1000, but this RL25 load shoots so good i'm having a hard time deciding to burn up more of my barrel in load development.

good luck

I shot 180s and 210 berger VLDs. Both Retumbo, both sum MOA at 800 yards.
Even with a break the damn thing kicks like a mule. Awefully accurate for a straight stock remington rifle.
