I am fairly new to reloading and have only reloaded for a 30-30 lever action. I recently purchased a bolt action rifle in .223. As I have never used a bolt action rifle before I put together five cartridges with no primer or powder to cycle the action and get familiar with it. The load I intend to use calls for an over all length of 2.2” so I used that and measured it with my calipers. I recently purchased a means to measure base to ogive, so I measured that at 1.88” figuring out how to use it. When I cycled the cartridges thru the action, the bolt felt a little tight closing. I cycled three cartridges and then measured the base to ogive because I realized I might be pushing the bullet into the rifling. Now the base to ogive measures 1.85” on all three cartridges. I then cycled these cartridges thru the rifle a few times and the measurement did not change. Would this be an accurate measurement for my base to the rifling for this particular bullet?
