[QUOTE="MontanaRifleman, post: 778958, member: 11717"] I haven't loaded for several of these for while. As soon as it warms up a little and I get some powder and bullets in I'll be getting busy. For the 300 RUM, I am using Rem brass. Not the greatest, it lasts about 4-6 firings with max loads. I have a Sendero 300 RUM and another being built. In the Sendero I worked loads for 180 E-Tips, 98 gr Retumbo 3400 fps 200 AB's, 93 Retumbo, 3200 fps 210 Bergers, 92 gr Retumbo, 3130 fps Accuracy was about .5 MOA for all loads. The E-Tips were most accurate out of my rifle. Bullets were seated to about .020 off the lands and too long for the mag box, My new build will have a longer mag box. I will develop loads in the RUM for 200 CE bullets and 230 Hybrids. I will try Retumbo and RL33. Yes, I chrony. I will be order an acoustic chrono this spring. And yes, The 300 Rum will be used for hunting. [/QUOTE]
