Forget the label for distance to dial out parallax... that is not close enough for the accuracy you are looking for.
Aim the rifle at your target so it sits there without your help.... then move your head around... side to side and up and down... watch to see if the reticle is moving... it almost always does... then adjust the parallax until you can move your eye around and the target and reticle do not move in relation to each other no matter where you view it from in the scope.
Are you using full length resized cases or are they fire formed and only neck resized?
Weight sort your brass no matter who suggests that its a waste of time. If the cases weigh the same and they are fire formed to your rifle and only neck resized, then they are volumetrically identical.
Tolerances add up... nothing is irrelevant. The more identical everything is the less total variation you will have.
That's not an inexpensive scale, but it is not all that accurate... it's rated to increment at 0.154 grains. Mine is accurate to 0.00154 grains... Vibra HT.
Make a validation weight for your scale... cut a piece of wire to weight the same as your powder charge plus the weighing pan. Once you think you have the right weight... double check back and fourth a couple times switch between the wire confirmation weight and your pan... make sure you get the same value each time.
Alright,
Parallax, will have to make sure it's set up right. This could only help.
Resizing, I resize the case every firing. Redding body die, which bumps the shoulders 2 thous and resizes the body dia a little.
But, if I resize every firing, shouldn't my body dia be as constant as if I wouldn't resize and only did necks?
I am bringing it back to the same spec every firing...
Weighing brass, I may get to it. Let's say it could be something I do to obtain the personal record, and then nevermind for regular shooting events.
Scale, 0.154 grains or 0.0154 grains?
I thought my ex RCBS chargemaster combo was 0.1gr and this one 0.02gr.
Like anything there must be more precise, I do believe that my FX120 combined with auto throw and auto trickler, is a happy medium between budget/reload speed/accuracy.
For the moment, even if i'd wish for more accurate in powder weights, the budget is limiting, as in the next coming months i'd love to buy several thousand 175SMK and CCI BR2, and a few 8lbs jug of Varget.
Just for the sake of not running out of components before the 2020 us election, I personally was blocked many reloading components in the 2012 election, I won't again.
Validation is already done. 42.7gr today is 42.7gr tomorrow. Got this deformed 175 SMK bullet I keep close. Give it a good wipe clean before putting in pan, and scale always registers it at the very same value.
