I am reloading for my Remington 700 in a .223. I've posted questions before and everyone has been super helpful however I am running into an issue with figuring out my OAL. So I sized my brass then trimmed it the desired case length and then I seated a bullet and coloured it black with a sharpie and then put it into my rifle and closed the bolt but when I take it out I can't see any markings where the bullet is touching the lands, am I doing something wrong or is there another way of determining without needing extra equipment? I feel like the bullet needs to be seated deeper because the bolt doesn't close smoothly. Thank you in advance.
