[QUOTE="swampratt, post: 3744229, member: 15054"] Those plastic tips get dinked around in the box and in production so the OAL will not read the same. Take one of your rounds that you are seating the bullet into and seat it to 2.840" and color the exposed portion of the bullet(projectile) With a permanent marker. Now chamber it and then extract it. During extraction it will usually pick up a scratch from the action on the way out. What you want to look for is rifling marks near the fat section of the projectile (bearing surface area) No marks then you are not in the lands. Now you can have deep marks about .030" long and you will know you are in the lands that much but that does not mean it is jammed in the lands. That is how I do it. Jammed and then back it off .020" Now another thing you can do is measure from the base of each bullet to the ogive and sort them like that. You will be amazed at how much difference there can be. Deeper and deeper into the hole you go. [/QUOTE]
