I bought a LEE anniversary kit about 3 yrs ago and have been happy with but the only problem was the scale. it would move when i had it set by a 1/10or 2 after just a couple of loads. The locking mechanism just does not work. i finally had enough and ordered a new Dillon Elimanator scale. Has anyone used this scale before? Looks similar to a RCBS 505 but not as much money. any info would help?
