Most Popular powder for the 300 RUM with 180 grain bullets

There is a very similar post referring to 190-210 grain bullets already on the site, but I am getting ready to load up some 180 grain Swift Scirocco's and would like to get a good idea for what is working for 300 RUM shooters. At the moment I have the following on hand - Retumbo, H1000 and RL 25. However, I am not opposed to purchasing something different if need be.

Thanks in advance.

    I've had great luck with 180 Siroccos and RL-25. I got a half inch group at 200 with it. Ironically I was not able to get that good of a group at 100. Go figure. [img]/ubbthreads/images/graemlins/confused.gif[/img]

    I have been trying to hit my 1150 gong with 180g btips and retumbo. Not very consistently, but thats a long ways off for a hunting bullet, and trying to compete with the 10-15 mph wind. Anyways, my load is accurate using 95g retumbo. I shot a 4 inch group with it at 500 yards before I swung over to the 1150 gong. So that made me feel halfway good. velocity is right at 3300fps. I have also had good luck with H-1000 using 96g, but that was with the 180g ctbt's. Velocity was 3330fps, and it grouped just as well as the Retumbo load at 500 yards.

    Retumbo is the best I have found for top velocities in the 7mm and 300 RUM. That said, H-1000 and Rl-25 along with Ramshot Magnum also produce very good performance from rifle to rifle. If Retumbo does not perform as youlike, I would look at one of these others first. You will get a good load with one of these powders as long as the rifle is mechanically sound.
