I made highmaster F-open with a dasher using an RCBS Charge master.
I purchased a used 10-10 balance and tuned it with the help of
@BoydAllen . When I started using it, I discovered my groups shrank and x-count went up a fair bit. For the purpose of doing some experiments and speeding up the loading process I bought an FX-120i and auto throw/trickler. I was worth the investment for what I like to do. I actually consider it an indispensable tool in my loading room.
I do shoot mostly at 600 and when I get a chance I shoot 1000 yards. I shoot F-class and IBS.
I did a little experiment a while back that you might be interested in.
I will not post the data as the haters and keyboard hacks on this sight breed like rats yet, I never seen their names in the top ten finishers at even the local shoots.
I loaded 5 rounds each of the following.
1.) Dispensed and weighed on CM
2.) powder thrower to get close and trickle up using the CM scale and trickling just to where the 10th rolled over.
3.) same as #2 above except used a tuned 10-10
4.) Same as #3 above except used a tuned 5-10
5.) used the FX-120i
6.) used just a powder thrower.
These were shot round robin at 600 yards.
Results
2,3,4,5 were the same
1 was good
6 not as good
Surprising enough, if you tune to the middle of a wide node, it will hide a multitude of sins.
I believe the CM must have some setting to “look the other way” if after trickling up the charge isn’t exact.... because mine will lie to you. When not using the trickler, it is as good as any other scale in the price range.
I will add, the time savings from the FX-120 is worth every penny.
Edit
To really answer your question, I mostly shoot at 600 and 1000 and think it is needed if competing at the higher levels.
