Have 3 , 1 RCBS , which I well , just hate it , simple., and 2 Lee hand primers , my hands fit the old crome handle one much much better , I tried new model I bought , 90230 , my hand just doesnt fit well like the old model ,about 47 years ago. I was more tiring to use for 100 to 200 primer loading sessions , so there it is , and never use the trays , ever. I like my old face and fingers.But life moves on.
