DAA Magnetic Powder Check 2.0
Using it on 6.5cm with h4350 it is not repeatable. All powder charges were verified on a sartorius scale with resolution to 0.02 grain, about 1 kernel of powder. The daa powder check sometimes sounded off and sometimes not on verified charges.
After the powder was weighed on the sartorius scale the case was filled thru a forester long neck powder funnel then placed back in the Dillon 750 for further cycle . The first of which was the daa powder check.
The brass end of the daa powder check would not fit thru the case neck so I had to use the plain rod end. There should be something in between using the plain steel end of the rod and the supplied larger brass end which was too big for the 6.5cm case neck. A bigger foot over the plain steel rod end may have been more repeatable.
Also the sensitivity of finding the sweet spot of the alarm can be a pain to find with the rod setting on a good powder charge. By the time you get the wrench into the magnet set screw you are compressing the powder charge, which makes the adjustment of the magnet void. Even pulling the rod out, marking magnet location and then adjusting magnet position was no help. They should have kept the sensitivity adjustment screw on the unit itself, or one that fine adjusts the center point of the go and no go point of the height range.
In short they need to come up with another brass end that will fit 223 and 6.5, they need to come up with a fine screw adjustment on the daa not the rod that adjusts the center point of the magnet sweet spot of the desired powder charge. As it now comes it may be 50% reliable, but 50% for a alarm is not acceptable. Concept is good, it just is not ready for prime time, needs more refinement. Tried for a 50% rating in stars like the unit performs but the program will not allow, so I settled at 2.
