Anyone know what size the primer hole is supposed to be on a 17 Hornady Hornet. I've been fire forming factory loads and when I go to prep the cases they seem to be all over the place. They range from a little over 60/1000s up to 80/1000s. In my case prep I've cut them all to the standard 80/1000s but was considering setting some with smaller holes and doing a comparison of small holes (around 65/1000s) to those I already have cut to 80/1000s. Any feedback on this or am I just wasting my time? On such a small case I was wondering what effect I should have in having smaller flash holes. I'm using AA 1680 which is fairly easy to light.
Thanks.
Thanks.
