300 RUM Brains Trust

[Aussie Wanderer]

Hi all,

I am about to embark on the 300RUM journey, once I have a set of dies. Is there anything unique about this cartridge that I need to be aware of? I was planning on using 200 grain Accubonds or 200 grain Barnes LRX. Retumbo looks like a pretty handy powder.

I am really looking forward to seeing what this cartridge is capable of.

Any thoughts, stories or starting loads would be greatly appreciated.

Hi mate. Another Aussie here and have just start got my 300 rum loaded up. Using 200 grain Accubonds and retumbo (adi 2225) powder. Shots great and looking forward to trying it on our Sambar deer.

Man, it took me awhile to come around to the RUM but man what an animal! I’ve shot 165’s through 220’s in mine and it seems like everything from H1000 up through VV570 work great. Currently shooting the 189 Hammers at an easy 3300 in mine. Very accurate cartridge in the couple rifles I’ve been around.

N570 and 230gr otm at 3150 fps 1/2 moa in a 26" barrel for me. Speed freak!

200 gr Accubonds and a healthy charge of Retumbo works great! It was one of the early "great" combo loads when the 300 RUM was released. Shot very well from mine. Excellent velocity and accuracy.

Recoil can certainly become an issue in a sporter-weight rifle...

I use to shoot R25 and 180 Ballistic Tips. I shot a buck at 813yds with that combo running 3450fps.

Since you didn’t mention any distance of shots , I would go Barnes under 300yds and the Noslers over 300yds. Big 30s can stress a bullet at closer range. I tried many bullets in my 30-378 before settling on Berger 230gr Hybrids for deer.
