I had previously read the info concerning Remington 1 1/2 and 5 1/2 primers in jwh32's post. I have used both successfully, and prefer them in certain loads. The 5 1/2s work well for me in .357 magnum jacketed loads with Alliant 2400 and they should work fine in 9mm if they stand up to .357 pressures.
