I had a R700 re-barreled to .280 Ackley by one of the barrel manufacturers. Been doing load testing. Cases are measuring .4772 at the expansion ring just ahead of the web. Saami drawing show .4710 all dia. +.002. I have another .280 AI That measures .472 fired and is very easy full length sizeing. Case life is long. These cases take quite a bit more effort to size and I am worried the case life will suffer. Not what I expected and looking for opinions , expertise on the subject.
