I almost get,but not quite the diameter of my bullet seated in the neck if I am just touching the lands with the 52 gr.,but almost nothing with the 55gr spire points.The 70 gr. Speers look good,and so do the Sierra 63 gr..I am surprised by the Winchester 64gr Power Points.They are designed funny,or I have a bad batch.I had never used them,but Midway had a deal on them,and I bought some.They look like they have a long bearing surface,but they don't reach full diameter till just a hair above the base.You can't even tell until you measure one.
