Mine is been an invaluable reloading tool and has paid for its self many times... however its never moved in 10 years maybe thats why mine has been perfect. Is also sits on a good bench with a shock mat below a rubber mat basically
I have used it to load rifle pistol shotgun.
I think people seem to think that is a super accurate scale at least thats what they keep comparing it to.
Personally I wouldn't reload if I had to use a scoop and a scale to do my loads it would drive me nuts.
I love punching in 45.0 Grains and Dispense... so what it ocassional throws a light or overload you just put the powder back in and press dispense again... It allows you to reload match grade ammo quickly. While my dispenser is doing the powder I am generally priming the case its going into saves time.
If your looking to have every charge idential to the indiviual powder kernal maybe its not for you and you should have a scale in a constant pressure chamber or something in a clean room atmosphere.
Cool thing about the Hornady one is it beeps when its done and it has an auto feature which I really like as soon as you set the powder pan back on the scale and it re zeros it automatically dispenses the last load.
Sometimes I forget to press dispense on mine
Somehow the Hornady one is also priced much less then the RCBS unit about 30-40% less, if I had to buy another one again i'd probally go for the Hornady machine this time around.
