Difficulty Seating Flat Based Bullets

Every few rounds, I encounter difficulty seating a bullet. That is, the initial start of bullet seating shows higher than normal resistance, and then it suddenly gets much easier, feeling like other bullets that go in easily with a consistent resistance. The bullets are flat based and wonder if they are catching on the case neck edge when first started. I feel I have deburred the inside of the case neck adequately, but maybe not. What might be happening. The components and tools are:

Forster Co-Ax press
Forster micrometer type bullet seater
Forster full length resizing die
Winchester brass (both new and fired, and always deburred)
Sierra 52 and 53 grain flat based bullet

Thanks.

Your neck tension is too tight. Just my two cents Tommy Mc
