This is what I got from Bob Blaine at Berger for the 153.5. Will try them out next week when I am home. I bought some loaded ones from Berger and they shoot very well at 100-200yds so far(new Sig Cross) so far. 2548fps. SD7
I have a two part OCW spreadsheet that makes nice neat calculations thats printable. Got it from somewhere but cant remember where. I can try to email it to you, wont attach files here for some reason
