Next week I will start working with my new 300 Ultra.(29.5", 1-10" twist barrel) I would like to try and find a load with the 240 MK. Could anyone give me a good place to start. The best powders that I have on hand are; RL-22,IMR-7828, H1000, RL-25, And Ramshot Big Boy. Of course I am open to other suggestions as well. I am also interested in opinions on weather I will be able to stabilize this bullet, and if I will be able to pass the 3000 fps mark, at my 4200 ft elevation. Thanks for the help.
