    Primer seating depth?

    Regarding "variance from rim thickness", while that's true for almost all primer seating tools, it's not so for the Lee ACP (which I have and use) and Sinclair has one that won't index off the rim thickness. :giggle:

    Chambering issue after expander mandrell.

    Agree. In my tests, I found running a mandrel through properly annealed necks did indeed move the donut out. . . as I stated here: https://www.snipershide.com/shooting/threads/chambering-issue-after-expander-mandrell.7252138/#post-12080340 I suppose I should mention too that when I run my...

    Chambering issue after expander mandrell.

    Hmmmm??? Are you suggesting that every time a case is consecutively annealed (like at the same temperature for the same amount of time) the brass gets softer each time?

    Chambering issue after expander mandrell.

    The best way I found to find out what's going on with the donut is to use pin gauges. I know, few reloaders go to the expense of having pin gauges to take measurements. I did and, for me, I like what I was able to learn by using them. Running a mandrel through the neck does move the donut to...

    New Lot CCI 450 issues

    Since virgin brass is really not all that uniform in their dimensions (why typically fire forming is done before load development), that pretty much explains the problem for me. That being . . . those particular cases of your lot were too short. :rolleyes: If they haven't been fired yet, you...

    New Lot CCI 450 issues

    Are these virgin brass? I suspect the case's headspace are too short. Such a thing makes it where the case is pushed forward enough where the firing pin won't deliver enough force to the anvil inside the primer to cause it to ignite. The primer surface still gets indented, but it's being...

    Chambering issue after expander mandrell.

    That's possible. But doesn't quite seem likely since he's using a bushing die and a bushing die doesn't size all the way down to where donuts develop. I wouldn't think the mandrel would open the neck enough to effect where the bushing die doesn't do any sizing. Therefore, there's no effect on...

    Which thing made the biggest difference?

    A very good barrel and the right bullet for the distance.

    New Lot CCI 450 issues

    It's really hard to tell in those pictures as they kinda look a little light, but not enough where I wouldn't think it'd keep them from igniting. The other place I'd take a close look at is the case headspace; a short case headspace can cause this issue too???

    New Lot CCI 450 issues

    Seems to me, being .005" below flush is a good place to be. Of course, it depends on how deep you pockets are??? How did the primers look in term of how the firing pin struck them? Yeah, check with that spare bolt is a good idea. It might be a firing pin issue is you're looking at light...

    Fouling past the case neck

    Yes, it could be an annealing issue. You might describe your annealing details. If you're flame annealing, be sure to get the necks to start glowing red, just for a second before dropping them out of the flame. And to get there, I wouldn't think your necks would be in the flame more than 9 or...

    Fouling past the case neck

    Well, obviously, the necks are not expanding quick enough to seal things off to prevent that from happening. I think it going to take some experimenting with different things to locate just what the issue is. I think DHDeal made some good suggestions as to what might be at issue. One need...

    Hornady high speed 3 in 1 case trimmer

    That cutter needs some kind of adjustment! The chamfer should be on the inside and not on the outside. . . and the deburr on the outside instead of the inside. :eek:

    .308 Winchester

    That's a bit low from all that I've seen on the 175 SMK's. Sierra website state a G1 BC of .505 for the 175 SMK's and the default for what's in QuickLoad is also showing .505 for that bullet. The 168 SMK's are shown as a .462 G1 BC.

    Primer seating depth?

    Yes, seating primers to the "exact same depth beyond flush" you get variations in they amount of anvil crush and distance from the bottom of the pockets. . . unless the pockets are uniformed. Also note that from a study done a few years back to see how consistent hand seating primers was, it...

    .308 pressure issue

    Likewise, the RPR's have a lot of free bore as well. I've loaded 168 SMK's where the case necks were holding onto only ~.185" of the bearing surface and .010 off the lands. It's not a problem for hand feeding, but I don't think I'd want to load them that what for mag feeding. ;)

    $$:SD

    Just the 2 major things I found that I can buy that really helps is having a really good barrel mounted on my gun and secondly a good scale that's consistent, fast and accurate (like weighs down to the .02 grs). A lot of the other stuff helps, but this is where I found the biggest bang for the...

    SEMIAUTOS - SHOULDERS GETTING BUMPED UPON CHAMBERING

    Variability! With the bolt slamming shut and moving the shoulders back .004 to .005, is that going to happen for every cartridge? I think not. When sizing cases, it's hard enough to get shoulder bumps consistent in a .001 range, even when annealing is being done. Matching headspace by +/-...

    ADG brass charge weight reduction? 7 PRC

    No. I'm saying that's how much difference in case volume I found. But I did have to make a small adjustment to get back to that MV. Yes, just FL sizing.

    ADG brass charge weight reduction? 7 PRC

    Probably! For my 6.5 PRC cases, my ADG brass is .4 to .5 grs less than my Hornady brass, which make a significant difference in MV. Most likely, you'll have to make an adjustment, given your Hornady load is a good one. No. Just keep in mind that I'll probably take at least 2 firings of the...
