posssum... I have only used one of the loads recommended on the EABCO site. I use the H4831SC loaded and 140gr AMax bullet. I started at 38g and worked up to 39.5, but my normal load is 39.2g. I full length size and trim after each use. Not sure the trimming is needed, but since the cases have had different histories (primarily different loads) I trim to keep them all the same. I've been meaning to call EABCO for a recommendation for trimming and also a 120 gr load. I hear alot of people speak highly of the VV powders, but have never seen any in the shops where I buy powder (pretty much just IMR, Hodgdon, and Winchester). When I called to ask when to expect to replace the brass, the answer was I should be able to several reloads (he said a number, but I don't recall). I don't have a chrony, so can't comment on velocity (maybe Christmas!!!).
