Base to Ogive measuring!

[squid]

Well I came up with a way to measure base to ogive of a bullet using what I had on the bench. Take the top off your wilson inline seater, flip it upside down so that the seating stem is sticking up, place it under a dial indicator mounted on a post and line it up, place a bullet in the seating stem under the post for the dial indicator, I like about 20 thousands of pressure, reset the dial to zero, and then just start measuring bullets very fast and accurate.
What do ya think??

I like it.

Keep in mind that the seater stem diameter is usually less than the actual ogive, so you're getting something less than true base to ogive measurement. But, since we're really just looking for relative comparisons between bullets, this still provides a valuable sorting result. And this would certainly be better than just measuring bullets from base to tip, which brings meplat variations into the picture.

You could also just do the same thing by putting a neck-sized case under the dial gauge with the pointy end of the bullet in the neck.

why not sit a sinclair nut comparator on the ram and drop the bullet in, then raise the ram against the indicator?

this will get the ogive.
