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 !
