[QUOTE="kc0pph, post: 551430, member: 35934"] I have a set up for pistol charges in my 357 when i am not doing max loads to us a digital scale. Its really easy to hit the tare button and its super fast. I tare the scale to the case, then throw the powder in the case, then weigh it. All im looking for is a GROSS under or over charge. The way i see it is this. For sake of argument lets look at my 357 mag. At one time i ran it up to 7.8gn 231 with a 158 gn cast bullet. I had slight primer leakage and slight primer flattening (if i remember correctly.) Now if i use a scale with 1 1/2 margie of error, and trusted it i could come out with 9.3 gn of 231 in it. That is what you call a ruptured cylinder (although i think a 586 can take it, as it is a super strong 357), and a trip to the trash can or a gunsmith to get you a new cylinder/barrel installed. I think most can agree, if you are willing to spend some money on a scale that does not have error, and willing to protect the strain sensor in it then go for it. But for under 100-150 go with a beam balance. You CANT go wrong with a good RCBS scale. A note about the 505 scales, i have one it is junk. RCBS cheapened up the scales. Grab a good old 10-5-10 (i think it is). (My father deals a lot with electronics and knows a lot about electronic scales, when he calls me back ill post with the scientific explanation of why cheap (most scales under $400) digital scales are dangerous.)
