My reloads from two different semi-auto half the time the bullets "Keyhole".
Thinking moving the bullet faster might cure "Keyholing"?
If the round cycles, its fast enough. I think you have diff issues. Usually keyhole is an undersized bullet or damaged bullet base of damaged criwn on the muzzle. I've run 185gr diwn at 700fps for speed steel, no keyholes.
