Does anybody have load data for the 340 Weatherby shooting 265gr or 285gr bullets? Most books only go to 250gr. I'm shooting a Weatherby Accumark if that makes any difference. Right now, I'm looking at the following recipe that I derived through some comparisons and simple calculations: Barnes 265gr TTSX H4831sc powder Fed 215 primers 3.675" COAL I calculated that a starting load of 76.0gr would be safe and working up from there in 0.5gr increments. Expected velocities should be around 2550 - 2650 fps. Thoughts?
