[QUOTE="Charter, post: 25713, member: 1123"] Has anyone tried the Retumbo powder in the 300 Ultra. The listed valued for a 180 gr. Speer SPBT are (MAX) 100.5 at a velocity of 3300 out of a 24" barrel with 62,300psi. My 300 has a 26", should I expect 3350-3400 fps? The bullet has a BC of .540 so it should carry pretty well. I am considering using this for hunting, but am concerned about the bullet not holding together at the close range velocities. Let me know what you think. Than [/QUOTE]
