[QUOTE="wheelgunner, post: 254205, member: 12831"] Hi guys, i have a "velocity" problem with my more accurate reloads. I made a lot of test, to find the best load with the Nosler Accubonds, in my rifles, TikkaT3.lamin/stainless 7mm.RM and Sako75 sinth/stainless .270WSM. The best accuracy loads i have found are theese: - 7mm.RM (TikkaT3) - 24" barrel Accubond 140 grs. x 66.00 H4831 Aol = 3,290" brass = Norma primer = Fed GM215M Vo = 2.850 fps. distance = 185 yds. group = 0.825" 5 rounds (with 1st. round - barrel clean) group = 0.472" (the others 4 rounds) - .270WSM (Sako75) - 24" barrel Accubond 130 grs. x 65.00 H4831 Aol = 2,870" brass = Remington primer = CCI250M Vo = 2.965 fps. distance = 185 yds. group = 0.787" 4 rounds group = 0.551" first 3 shots ...... why my loads don't go over 3.000 fps / 7RM and over 3.100 / .270WSM ? ... i really don't understand ! ... I would like to know your point of view about theese poor energy loads, consulting the Hodgon data manual (on line), i should stay about 1grs./1.5grs. less the max charge ..... but i can't understand theese results. i really don't want use a magnum caliber .... with the result of 7.08 or a .270w ... HELP ME ... :rolleyes: (The strange distance, 185 yds. , it is the max i can in my pistol-shooting-range) Thank you so much for your help. Luca [/QUOTE]
