Yup measured with micrometer. On the last 50 I got the case necks were almost all .010 to 0.011" thick, I had 11 cases that were .012. I ran them over my digital scale, the cases were all within 0.7gr. Just for reference my remington brass was all 0.015-0.018" neck thickness and was about 3 grains different in weight.Thank you, Long Bomber. I appreciate the info. Did you in fact measure the thickness of your Nosler brass? I have heard some negatives on that brass that has made me leary, but I'd really like to try it.
