Chris Rhines Posted February 10, 2008 Share Posted February 10, 2008 I'm having issues loading consistently accurate .223 ammunition in my XL650. Best I can do, having tried half a dozen different loads, different bullets, etc., is 3.2" CTC for ten shots at 200 yards off the sandbags. Not nearly good enough*. I load semi-progressively on the XL650, with a Dillon carbide sizing die, Redding Competition seating die, and no crimp. First go-round sizes, de- and re-primes. I trim the cases to 1.750" in my Giraud, then charge and seat bullets on the XL650 again. One possible problem is with the sizing die. I'm trying to bump the shoulder back to 1.461", for a chamber measured at 1.4636". I can't seem to get consistent shoulder dimensions without cranking the sizing die way down, in the area of 1.457". Will having rounds sized so far under my headspace cause problems? Is the shoulder dimension even all that critical? I'm using Remington once-fired cases from a friend at a police range (i.e. they were fired through all different weapons.) Would it be worth trying some new brass? Anything else I should be looking at? Thanks all, Chris Link to comment Share on other sites More sharing options...
