To the best of my knowledge I've never loaded any compressed loads. At least the manuals did not list them as a "c". OTOH even Hornady's 8th edition doesn't even list 14.9 as compressed (I'll assume that it is!) After following a few threads on loading AA9 with 180 200 XTP's I'm confused. I laddered up using virgin Nickel Starline 10mm brass @ 12.6, 12.8 and 13.0 grains ( 1.260) which is well below Hornady's max load of 14.9gr. Other manuals suggest a much lower max. Now to the confusion: some have stated that 13.0 is a compressed load and in the same post referenced that the HP petals were a bit crushed in the seating process. Are these two unrelated statements OR are they suggesting that the deformed petals suggest a compressed load? I'm using a Redding Micrometer Competition Seating Die with zero deformation as it seats on the ogive. How does one determine that a load is compressed? One other question: after applying the taper crimp the rounds COAL increased .001-.002. Why? I pulled a test round to see if there were any signs of over crimping but the base of the bullet did not have any pinching. Thanks!
