[QUOTE="foggybottombob, post: 789242, member: 38894"] Weighing charges to the nearest 1/10 th of a grain is the minimum you need. I shoot short kernel extruded powder and sometimes have to pick two or three short kernels out of a pan on my RCBS charge master. It takes only 2 or 3 kernels of this powder to make a tenth of a grain. That might amount to 40 fps difference on the chrony. I use a high energy double base powder for the load I play with the most so other powders would probably not have that much velocity variation for a couple of kernels. But you have to be precise with your powder charges. I neck size for the first 5 loadings of a case then I anneal the neck and full length resize it to push the shoulder back 1 or 2 thousandths from where it is when I have first fired the case in my rifle. You need another comparator type bushing to measure where your case shoulder is with respect to the base of the case for any particular rifle. These comparator sets are only $30 or so. Of course you need a set of calipers to go with it. I think you already have that. I reloaded as a teen and barely knew what I was doing. It's a wonder I still have my face. But as a 56 year old engineer I think I understand it now. [/QUOTE]
