been a long time since I shot any 25'06's, used to be my go to rifle though. I got bored being tagged out on opening morning of deer season. Biggest problem with a .25'06 I had was if I could see it, I could kill it. I used to buy Remington core lokt bullets in bulk packs from midwayusa.com a near max load of 4831, or 4350 made 400 yard shots easy. 53 grains of 4350 made 3,250 fps, as did 55 grains of 4831, with the 100 grain bulk packed bullets.
