Received a box of 270 Barnes TTSX 130 gr bullets. I decided to use a tried and trued powder charge of IMR 4451 that has shot really well with multiple 130 bullets out of the 270. My 4 shot group is .510 inches. My velocity is right at 3000 fps at the muzzle. First attempt with this bullet and obviously it groups well so I kind of want to save them and not continue with load development. I know this load would be deadly on any deer walking. Is the bullet weight / bullet construction and velocity enough for elk in the opinion of hunters on here?
