    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 (That is above max ). 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!!

    Good to know, I still use the scoops and old pan scale.
    Sometimes I wonder who the old man in the mirror is....

    Lord, Grant me a good sword and no need to use it.

    I have used scoops, scales and trickler (still do for real critical stuff) but have found (normally) the Hornady measure to be incredibly accurate - like +/- 0.1 of a grain at worst - which more or less for plinking ammo is well OK.

    That of course is if I attend to tightening up what should be tightened up

    Discovering something went wrong is much better at the loading bench than out on the range!

    Exactly, when in doubt , pull and reload questionable ammo.

    Well - all 50 .223's pulled - what a pain in the petootie!!

    Seems like the main charge drift really began with the ones I started today and became suspicious of ..... most pulled were close to spot on but a few had definitely drifted toward larger drop.

    Better safe but - heck even with a collet puller it's tedious! Yet to check out the few .243's.

    Talking For less than 100 rounds

    in a session I use this, 15 seconds and any weight you dial in is there. Wanted one for years, then went on-line to check out which one was tops in reliability, repeatability, and accuracy, then Providence acted and Midway put it on sale, this was meant to be.

    Oh that is nice!!! me want!

    Trouble is my set up time is really not too bad, tho more than 15 seconds! Maybe five minutes but once set (and properly tightened etc!) - that Hornady throws good reliable drops ....... and as it's only used for rifle it will do.

    When set I try and do a large number of rounds ...... being likely to not load rifle stuff again for months. Hoping to get about 800 rounds of .223 loaded - at least, that's the number of cases sized and primed.

    Gotta throw this in for giggles ........ if perchance the case rim does not engage in the shell holder (careless operator!) - then the whole deal goes way too far in to die LOL

    This is way beyond shoulder surgery Ages since I did that.

    Scoop and beam scale for me. One of these days I'll have to upgrade to some nicer tools.

    Nah 225.00 on sale for the combo unit. N actually it is 15 seconds or less, funny thing though I wanted to see just how low it would go and at .4 of a grain it was slower than when I had it dump a load for the .416 with out going up and looking I believe it was around 60 grains only took about 10 seconds. N you work the OT you deserve the toy.
    BTY did that to a .416 case in the seating die, oops!

    I have 2 .45acp rounds that look something like that. They were my two first reloads ever and I messed them both up before I figured out what I was doing wrong. I keep them on my reloading bench to remind myself to really pay attention.

    Normally on on my rifle stuff I wieght/trickle every charge. In pistol & shotshell. I normally weigh every 5th load. It's more time consuming, but as a good friend of mine always says "Sometimes you've got to slow down & let your ***** catch up"
