300 Remington Ultra Mag loads
Just checking to see what velocities are folks getting with the 200 grain Nosler Accubond? And what powders are you using?

What have your experiences been with Hodgdon Retumbo.

Thanks,

I suggest you use Nosler brass instead of Remington brass for the 300ultra.Remington brass didn't work for me.

I use the 200 gr. partition and am getting 3100 fps with Ramshot Magnum. The load is from the Nosler book and is their accuracy load.

Can't recally velocity without my data book. I use the 200gr AB a-lot in my 300RUM with RETUMBO and RL25. Both shoot very accurate near max and at book (Nosler) max.

I use Nosler and Rem brass. Rem brass has worked as good accuracy wise for me in 300 and 338RUM. I do anneal them after 2 loadings. I find the Rem brass splits necks fairly quickly.
