When I load bullets that do not have specific load data, and that happens frequently I tend to be conservative and start a little light on powder. For coated bullets I use lead bullet data and since you are loading 135 grain, may not have load data for that bullet so in that case use the data for a heavier bullet, maybe 140 grain if available. Finally, observe the primers of your first small batch. Sent from my 710C using Tapatalk
