[QUOTE="mtJim, post: 2607160, member: 121886"] Got some more testing done this morning. A .273 pin gauge slid completely through the neck of all prepped cases. The .272 fit easily, .273 snug, and .274 wouldn’t go. I could not find any sign of a donut. Also, could not find any irregularities in the case mouths, at least to .0005. I tried loading another round and seating a little, then turn, seat a little then turn. This one would stick every time the bullet was fully into the stem, last week it was only at the end of the stroke that it would stick. My ideas now are to get a mandrel and lessen my neck tension for seating, since I am using a Lee factory crimp die anyways. And if that doesn’t help then try bedding the seating stem. I guess all this after just shooting it first, make sure I am not trying to create a problem where there aren’t any in the first place. It’s just driving me crazy after I’ve done the same thing for several reloads through load development, now things are different. The only thing that has changed is annealing. [/QUOTE]
