338 rum info

I've used IMR 8133 with the 250 gr AB in my 338 RUM with excellent speed and accuracy. I've shot both 300 gr AB and ABLR with Retumbo. With the 300 gr ABLR I'm getting 2830 fps. Keep in mind that I have a 27" Krieger barrel.

I only have 300’s very limited availability of components in my area. Thanks jd
 
Roger that. I think you should do pretty well with IMR 8133. The burn rate is similar to Retumbo.
