Reloading mistakes - ditch the nylon brush & balance beam scale !

[Magnum_Willys]

Made the mistake for a year of thinking my balance beam scale was more accurate than my Chargemaster.   Was using Chargemaster to drop charge and trueing up with balance scale.  Wth? Finally got an FX-120i scale a year ago and realized my balance beam scale was the one prone to errors.  Now every load is within 1/2 kernal the same.

I Now use chargemaster to drop within .04 gr then tweezers to add a kernel or 2

Made the mistake last couple years just using a nylon brush instead of bronze to clean bores.   With a $50 amazon borescope realized the nylon does not scrub the carbon all out.   Hit my bore with a bronze brush and could see steel again.   Did drop velocity a bit but back to 6” groups at 950 yd. 

Made mistake on under annealing - bumped it up a bit and now running single digit es on 300 gr Lapua. 

When it all works es is single digit.

6 shots at 950.   Load is better than shooter !

You sir, just got a new subscriber

That's a similar process I use only I am a bit more ghetto.  I use a Lee scoop, then trickle, then a tweezer if I need one grain more or less.  Glad I don't shoot F class or PRS.

What about the v3 auto trickler for the fx120i?

Thats likely what  I will end up with!

willy what is your annealing timeline for lapua? every empty? 3x fired, 5?   i have Cheytac and am segregating cases by fire times for this to determine "good" options on when annealing should happen....

I have an AMP so I just anneal everytime.   I segregate rounds too.  I bumped my setting up 2 points and got a much more consistent bullet seating.  All my rounds were within .001 in length to ogive and 2/3 were under .0010 runout and all under .0015 .   This is with 300 bergers.

I had to anneal everytime with bottleneck 338-378 cases so just got into the habit.   Very important to brush necks with stiff nylon brush after annealing.  I do 4-5 strokes.

I also spray liquid graphite in a small 1/2 pint jar, tilt it so depth when dipped just covers neck.   Dip, wipe outside of brass, place neck down in tray.
