[QUOTE="Michael Eichele, post: 248442, member: 1007"] With all due respect LV, I am not trying to calculate how to get to a certain velocity. I am looking for real world experiances and maximum velocities. Not neccesarily with a given powder. So if you have any experiance with this particular cartridge AND bullet combo, I would love to entertain it. As far as RETUMBO, I am getting 2940+ with 90 grains of H50BMG with room left in the case for about 5 grains. This is a retorical question. What kind of pressure do you think RETUMBO would generate in my rifle with a 220 SMK? I have pressure problems with RETUMBO in my rig with 180's as it is and TONS of room left in the case. Thanks but no thanks. 338 bores are bigger with more burn area slowing powder down. My tight chamber, tight bore 300 is not very well adapted to RETUMBO. [/QUOTE]
