I am shooting a 6.5 x 284 Shehane, it really likes the 140 grain Nosler Competition, but the bc isn't so good on those bullets. I would like to be able to shoot the 140 grain hunting vld. i do now, with a 20 thou. jump and they shoot great, but I want to be able to get them to fit my magazine. I do have a wyatts extended box magazine, so they can me 2.95 or so long. is that 120 thou jump too much? what determines the accuracy of the load, as long as they start straight shouldn't they shoot straight too, no matter the jump?
