Hi i got a ruger stainless steel barreal and synthetic stock with a millet 3x9x40mm scope own it and zeored it in at 50 yards i hunted in a bottom of a creek and killed my first buck a eight point with sixteen inch spread and weighed 240 pounds and i shoot him with a 150gr remi corelokt, it went straight through him and instantly droped him , i am hunting with a .280 caliber , so i went to sporting goods store since i wasnt satisfied with the bullet cause i wanted something that mushroomed up realy good so i buyed a box of winchester supreme 140gr ballistic silvertips and shoot a doe today a huge one about 100yards away she and seven othiers ran down a bottom so she stopped dead in her tracks and looked around so i raised my barrel and shoot her in the heart and it came in like the .280 diameter and blowend up and came the othier side of the size of a baseball, im hooked own winchester ammo for life im very pleased with the ammos performance she dropped like a rock, so i was wondering if yall thing the .280rem is close to the 7mm mag or what do yall think its simillar too
