6.5x47 case length

[tony]

I have just finished full length sizeing 100 lapua once fired cases "fired from my rifle" checked in my Berger manual for recommended trimmed length @ 1.840 but found that my cases were all measuring around .005 less than the recommended trim length so question, is this normal for this calibre? Should I trim them at a shorter length?

Have I completely lost the plot and buggered the cases?

Thanks Tony.

If you've simply FL'd them after firing once, there can't be anything wrong.

Def don't trim them further though..

I've used on many occasions .308 brass necked down to 7-08. They're way more than 5 thou short but still work fine.

 

My 6.5L brass just doesn't seem to stretch much despite running full loads. I am using Redding comp dies, only body bumping. Don't own an FL die.

I'm on my fourth load on what was virgin lap brass and I still have not exceeded oal case length . I've inside and outside chamfered and done the primer hole but still yet to take anything off the o all length . That's checking in a Wilson guage max and min limits , atb Ian

Thanks for your replies guys much appreciated, sounds like I have nothing to worry about, I am used to 6.5x55 cases and they need trimming every time! Just wanted to check.

Thanks Tony.

Tony - ultimately, your case-length is determined by your chamber. If it's a factory rifle there will normally be plenty of room for the case to grow. If it's a custom build, there could be very little. If it is a custom build, the builder can give you the chamber length - I trim 15 thou. off that.
