OAL, Ogive, Comparator
Ok I'm a newbie (reloading for only 5 months, only around 1k rounds under my belt) but I think I'm turning the corner.
I started this thread to see if I was on the right course or not.
When seating a bullet at a given OAL, it could seat deeper or shallower depending on if the bullet you used to set you OAL has the same ogive. If they don't, it could have a little longer or little shorter OAL.
The only way to be able to tell if it is the same distance from the lands, is to use a comparator, which measures from the ogive. I'm asking because I am trying to load more accurate ammo for my daughters .223 and for me 7mm RM and trying to make sure I have around a .02 jump.
I'm assuming that "match" bullets are more consistent in the making process, making the bullets in that lot almost identical (ogive, length, weight), which equals consistency when trying to shoot a match.
Am I on the right track of thought or not?
