    SAC sizer die setup?

    Have always ran my virgin brass thru a FL sizing die. Since Virgin brass is not formed it only gets the neck sized anyway. Just curious why that would ever be a problem?

    SAC sizer die setup?

    Lapua once fired. Sized with same sac when was Virgin brass. I anneal every firing. Annealed right before the sizing with AMP.

    SAC sizer die setup?

    Once fired brass. Fired headspace 1.499 with Sinclair comparator. Sized 1.497 but some are still 1.499. Fired neck 2.951. Sized back to .2894 odd with expander mandrel in sac die. When take expander out od is .2883. Try not too overwork brass. Like have done with Forster honed die for years...

    SAC sizer die setup?

    Have a question on my new sac sizing die. Got it setup like the sac sizing die setup video says. Got the decapping expander mandrel in it with a .288 bushing for my 6.5 Creedmoor. The bushing edge (facing the decapping end) is lined up about even with the top end of the expander section (closest...

    Guess I am not alone. I can insert it and get reading and do 10 more one after another and get different readings. Not just a .001 or .002 either. It's like it is galling slightly. And all the readings are about .005 less than should be. I sent mine back to check it out. I think they will get it...

    I appreciate the info. I better stick with my CPS since they aren't cheap and have been happy with it anyways. I doubt we can about the difference anyways.

    What I like is how fast you can check seating and priming depths. I am confident Accuracy One will get me lined out. I expect I am missing something dumb. Lol. Have Merry Christmas.

    Yes. Usually.001 to .002. Rarely more. However, this is only from measurements from Mitutoya calipers. My Accuracy One I don't trust enough yet to know better than that. Sending it back to AO tomorrow to get it looked at. Getting .005 shallower pocket heights than think could possibly be with...

    I think it's great. Very repeatable if brass and primers are consistent. Easy on e hands. CCI BR2

    Going to contact Accuracy One tomorrow. Have tested so many cases now and can't come up with a why. When I change brass brands or even lot to lot it will be hard to know how deep the pocket really is or if I try different primers. By the way I use a CPS priming system which seats very consistently.

    That's strange mine are .028 different in diameter. Still hard to believe it matters since I only get .001 difference in measuring from either end?

    Also, I only get about a .001 difference in measuring pocket with the concave vs flat end using the Accuracy One. So it doesn't seem to be an issue of WHERE I am measuring on the bottom of the pocket. I would simply use this tool as a comparator as Rio suggested, however, it bugs me that I am...

    Agree with you. Your last sentence is exactly what keeps me scratching my head though. I use the stem of my Mitutoya calipers and poke against the outer edges in 3 or 4 places on at least 20 pieces of brass on all 3 brands of brass with same lot numbers. I consistently get these variances...

    My stem was 1.438 long. Concave end diameter .2038 and flat end was .2066. Weird to have two different diameters for the stem ends.

    I completely understand and agree with all you said. Just bugs me that it is off .005 as average AND can't be a true number. Never heard anyone have Lapua, Alpha and Nosler ALL have pockets this shallow for 6.5 Creedmoor. Readings from Accuracy One are twice fired and Virgin Lapua .122, Virgin...

    Thanks! Will probably just get both. This tool will be very nice once I figure out it. I bought their bullet seating depth tool that measures shoulder to ogive and it's very repeatable and very fast.

    I will look at it again tomorrow. Otherwise, I plan to call the company to get some input.

    This appears to be a very simple tool but I feel like I am missing something stupid to be off so much. .003 to usually 0.005 less is huge difference in getting my seating depths correct.

    Which Mitutoya model and where do I get that tip?
