Hi, first time posting long time reading. Sort of new to reloading. Sort of learning as I go. Have a Remington 700 .270 Winchester. Maybe 800 rounds through it. Seems like I can go in and out of accuracy, could be me. Started with Sammi length then recently went .024 longer ogive. Bolt was hard to close and the were Mark's on the bullet from the lands. Got the hornady oall gauge it measured .129 longer than loaded round. Any help??
