[QUOTE="dok7mm, post: 1932772, member: 90080"] What compression?? You are dealing with 1/2 to 1-1/2 grain maximum to regain speed after you use HBN. I hardly ever have to increase charge more than 3/4 gr of powder to get back to accuracy node. A new barrel will usually increase in velocity until it stabilizes. Can be 75, or 100, or 150, or occasionally 200 rounds fired. You can use this time to do a barrel break-in, forming brass and initial seating depth & pressure testing. Then you can concentrate on load work-up. There is no reason to use one powder to develop a load, then change powder to use hexagonal-boron- nitrate. Pick a proven powder for your PRC. If you get a good load with bare bullets, it will work with HBN. [/QUOTE]
