[QUOTE="dmr400, post: 2535305, member: 33691"] Also, you need to research HBN loading, there are quite a few things you need to look at. Pressure will be lower, so powder charges will need to come up to get the same velocity. The bore needs to be seasoned with HBN after cleaning which requires either coating it with an HBN/alcohol solution or shooting quite a few coated bullets through it before gathering any data. If you use the solution method you should fire a couple of reduced loads with hbn coated bullets or you will see a pressure spike. There is quite a bit of good info over on longrangeonly.com about this. Personally I wouldn't mess with bullets that somebody else coated, you have no idea what process they used and how you would replicate it should you need to. [/QUOTE]
