I love these bullets! I recently retired the remington genesis do to inconsistent grouping after 4 years of effort, and bought a knight bighorn. I bought a box of .458 275 bloodlines. First 3 shots with 110 gr. of T7 2ff at 100 yards was inside of 1". I didn't think I was capable of shooting like that. I got my first shot on a small 8 point with them opening weekend in MI. I spent a couple hours creeping through a corn field looking for a beaded deer. When it started to get dark I left the corn and headed to my truck. As I approached the last corner in the fence row I paused and scanned the big open field, suddenly 8 deer darted out from the neighbors corn into the field I was watching, I found the biggest deer (not knowing it was a buck because it was almost dark) and settled the cross hairs at center mass and fired. I watched the black silhouette run about 50 yard and it appeared to be nose diving. I lost sight of the deer from there because now it was dark. I walked to where the deer was when I shot it and ranged back to my shooting spot and it was 150 yards. I headed in the direction that I last saw the deer go in the open field , and it wasn't long before I saw the black mass laying on the ground. The buck ran about 80 yards and piled up. Looking at my shot placement, I was surprised that this killed the deer. I hit the right front leg just above the elbow and behind the bone. The bullet then skimmed the brisket of the deer and passed through the other leg in about the same place. Upon autopsy, I found that 2 pedal from the bullet entered the deers chest and punctured the heart. Without the fracturing pedals I may have lost that deer. I'm A believer. Ive now also have been practicing longer shots at the range, because these bullets do drop more that the old spear tips that I used to shoot.
