excessive headspace

[pitdog85]

So I stuffed up resizing a case for my 6.5x47l the shoulder has been bumped back around 30 thou. It has been annealed. If I was to fire it will it resize back to chamber size and be able to be reused as it has been annealed? Or is this simply too much and the case is likely to rupture or something first shot thought this would be the appropriate section to ask this before trying anything stupid? thanks

I used get excessive headspace all of the time. Then I quit doing acid.

I don’t know if the case would rupture, but .030” is way too far. Typically you want to bump the shoulder maybe .001” or .002”.

thanks mate I normally only bump them back around 2 thou but I stuffed up setting the die with this one just not sure if I can fire it and reuse it once its sized back to chamber or not

Load cases as if you were fireforming . IE : if you have the
correct tools to accurately measure base to ogive of your loaded
round , and tools to measure distance to lands , you can seat the
bullets for a 15 thou jam . Hopefully you can blow out the front end
of the case to its correct dimension .

If if you have a unfired 6.5 x47 case , measure the base to shoulder
compared to a non resized , fired case from you chamber . I get
1.383 for unfired , and 1.391 fired , obviously Lapua case can easily
cope with an 0.008 stretch .

Just firing the oversized cases without jamming the bullet may result
In overstretching and damaging the case . Most likely your usual load
is jumping to the lands , so reduce the powder charge half a grain or
a full grain to be safe with pressure , especially if you are running a hot
load around 40 or 41 of H4350 .
Proceed with caution , check for pressure signs carefully .

thanks mate that's great advice will follow that.
