I would repeat the ladder but load the cartridges individually instead of feeding them through the magazine. If you don't have good neck tension with your reloads, this may tell you something. You'll have the "smack" of the bolt closing on the cartridge in the chamber but not all the inertia of the first round's recoil/eject then the strip & slam into battery of the next round, etc.
You could also bring your caliper to the range and measure once before and then after manually putting the round in the chamber and dropping to bolt. (Just eject it and measure).
Not sure if you can shoot at 100 yards or not at your range but 50 yards doesn't tell you a whole lot. Sighting in a scope at 50 yards until it's dead on then moving back to 100 can and has given wild variations in accuracy on many calibers I have shot over the years.
