[QUOTE="CogburnR, post: 839097, member: 29174"] I have a 270 Sherman which is a blown out, lengthened and improved 270win. It holds about 10% more powder than a regular 270. I currently use 64gof RL22 with a 130g Berger which is 10% over the max listed for RL22. If I understand correctly a 270 AI has about 5-7% more capacity than the 270 Win and would likely have powder charges around that much heavier than the 270WIN.So you could work up loads up to 7% over book loads for the 270 and be in the ballpark(start that much lower also and work up).
