[QUOTE="mrultramag, post: 953121, member: 4467"] I've shot retumbo w/200AB in 300 Rum. I think I went as high as 95 gr looking for tight groups. For my gun-Rem 700 (26in bbl)- RL25 92 gr is more accurate and gives me 3150 fps. That is about what you should expect velocity from retumbo as well. Many people get 3200 with retumbo and the 200 AB but may be leaning on it a little. This is using a 26" bbl and Remington cases. Nosler data for 200 gr is using nosler cases and 24" bbl. Shorter bbl= less velocity. Different case=different capacity. work up your load. use a chronograph and watch for excessive pressure signs. [/QUOTE]
