Regular neck-sizing ain’t all it’s cracked up to be. Partial FLS is how I handle my hunting loads. Been doing it for a couple of decades. When brass sized that way no longer chambers, it’s time to FLS, and maybe anneal, or even toss the brass.
Pull the bullet on a couple of the tight ones and try to chamber the case again. Measure the outside neck diameter of them first. Check the case length.
