Mine is a 338 RUM with a Lilji barrel, it will be completed with brake and all next week. I have not shot it yet but have shot their coating in everything else, if you know how to read pressure in a case you will see at max loads you are not showing signs of pressure. No one will tell you that you can load over book max and I won't either but I worked mine up from the middle and all of my coated loads are at least max.With a 3,000 fps rifle 60-80 fps increase would be an average, but ask Tyler. You will get the advantage of less friction and the max load. If you look at 2,950 + 80= 3,030 and what rifle would launch that? If you look at your reloading manual 100 fps is the difference between regular calibers and the hot shots and some magnums. If you send quantities they were charging $40 per thousand plus shipping back to you. I sent everything 338, 223, 30 cal, 270 and told them to do them all and I would sort them when I got them back, the bullets were different enough to tell at a glance and then I get the combined bulk rate @ $40 per.
