You really think that the bullet in a 9mm is engaging the lands of a handgun at 1.049"
It was only that bullet 124gr berry. Everything else (hornady, montana gold) was longer. When I tested my OAL I would use 3 cases of equal length within spec. These were fired cases that hadn't been re sized or flared. I made sure the case would slide in and out easily before putting a bullet in. I would push the bullet in and work with them.
