Lyman top punches

Something else to consider. Sometimes, it's a good idea for the seater punch to “float” a little. Some lubrisizers have a misalignment issue between the ram bore and the die body. If the top punch fits too snug, it can push the bullet into the die slightly crooked and the result can be a crooked or bent bullet or one sized off axis. When they can be used the flat nose punches help solve this. For a fitted punch, I like for mine to be a slightly loose fit to the nose of the bullet. The application for the “correct” seater punch is usually only close because manufacuring tolerances and production run variances can yield a puch that will not be an exact match. This has prompted the JB approach to get a good fit. Instead, what I do if I have a nose punch that marks the ogive of a particular bullet is to reshape the punch to a loose fit. I do this by chucking the punch in a cordless drill and spinning it and then slowly dress the contour of the punch with a Dremel tool. Also, I don't run a bullet down into a die with a quick, single stroke. I give it a small start into the die then back off slightly and then again press it further to be sure it is entering the die straight, especially with long bullets. Shorter stubby bullets are less prone to issues of misalignment.
