So i see a ton of information and videos on people having a lot of fun and great experience with powder coating bullets. What i have not seen is information like if a bullet designed for a gas check still works well and what the new velocity limits would be. Is the powder coat as good as a gas check at preventing leading while shot at full power loads. Does powder coat completely remove the need for gas checks on all bullets at all speeds. My specific area would be the common lyman 155 cast bullet with the dual crimp rings in 38 and or 357. Should a custom mold be made or modified to remove the gas check in this bullet if powder coat is used???
