Need 338 RUM load data for 250gr bergers

cb4128 · Sep 18, 2024

I'm in Need of some 338 RUM load data for 250gr bergers. I have some really good data for the 300 RUM with 230gr bergers, but I realize it's a different case, with less powder capacity - so just trying to find a starting point for N570 and Retumbo powders.

Unfortunately, Berger's load data online only has N560 and H1000 - neither of which I have.

Thanks for any help!

My go to load is 96gr of retumbo. Start lower and work up. Good for around 2950fps in most of the rifles Ive used it in. Wish they would start making the 250bergers again. It's the perfect bullet for the 338 rum.

I think the USS Iowa was using (4) 75lb bags of powder under that bullet.
