If you look at almost any reloading manual 9 times out of ten the powder charge gets bigger as the bullets get lighter, example-hornady sixth addition, 223 50 gr V-max h335 max load-25.7, 45 grain hornet h335 max load 27.1, 40 grain V-max h335 max load 27.4. I have always used 40 grain data for 35 grain v-max's with no problems.
