A charge weight check - warning.
Just a write-up on how charge weights can go astray! Hopefully reminding other reloaders how much we have to stay on the ball.
Below is a small pic of my Hornady measure - gets used very little as only needed for rifle reloading. Last time used was year or more ago to do some .243 rounds with N-140 - fortunately not many I am thinking.
Yesterday, changed powder and set it up for N-133 to do some .223 rounds - long overdue. After experiment and weighings - got it set and dropping the 24.5 as I wanted. Proceeded to load 50 rounds.
Today started on another 50 - but after a few powder drops my spidey sense was tingling - maybe cases looked a shade too full by a smidgeon.
Checked drop and - horror - it was up to 25.5 or so :eek: (That is above max :gah: ). These will all have to be pulled now - and the remaining .243 rounds too (cases had shown some primer flattening but don't think charge had gone too much over - we'll see!).
Cause??? Look at pic and you'll see on the left of the rotating block, what is an Allen set screw, which secures the micrometer measure insert. Ahem - it was not fully tight!
Each time I drop a charge I move the arm slightly a coupla times in the up position to ''knock free'' any grains hung up in the discharge tube. Gradually that had allowed the insert to creep out and so up the drop volume. Glad I checked!!
