    Neck Tension Inconsistencies on Lapua 6.5CM Brass

    Speaking of engine oil. . . Back in the mid '70's when I had been working in the aircraft industry, a bunch of synthetic oils for auto's came out (synthetics was normal for aircraft and I always wondered why not for autos). One of the oils that came out touted how effective their additive was...

    Chambering issue after expander mandrell.

    If one has a bolt that has a spring loaded ejector pin, that pin puts pressure on the cartridge as you lock the bolt down, which will push that unsized portion of the neck more tightly into the chamber and this is where you get the more centering effect. Otherwise, the looseness due to...

    Neck Tension Inconsistencies on Lapua 6.5CM Brass

    Maybe ditch that expander ball and get a ball with a better design? Or better yet, ditch the expander ball all together and expand the neck with a seperate operation with an expander mandrel??? I find the latter to produce much more consistent results.

    Chambering issue after expander mandrell.

    Because bushing dies don't size all the way down to the neck-shoulder junction, is the reason I use a non-bushing FL sizing die. But. . . there's something many reloaders like about the bushing die other than controlling and minimizing the work put onto on the neck, which is. . . that part of...

    Primer seating depth?

    I'd say when one is happy with their process . . . IMHO, that's all that really counts. :rolleyes: :giggle:

    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...
