OK, on paper, it seems that N540 and H414 might work well in my 270 wsm with a 150gr Berger and my 223 with a 40 or 50 gr vmax. One powder, two diff cal guns? Could it be so? Or does it not translate from the web to the target or through the chrono? Since Vit seems to be hard to find I might try the Hogdon. Has anyone tried the 414 in 270wsm 150gr Berger (looking for 3,000fps) or the 223 with a 40gr vmax (around 37-3800 fps)? If not either of these what about Winchester 760?
