I think I did it right. I did it the way in the video somewhat. I barely placed bullet in my case and seated it. After doing the process I noticed markings And then a little ring, which I would guess be the land? There is no way in my AR to make that length possible because magazine allows 2.290". Will I still be able to use the load I developed and not worry about pressure? I will load to that length and see what happens. I am going to gain investment in a comparator to make seating depth easier because the tips of bullets have varied and is aggrevating a little.
