[QUOTE="Rich Coyle, post: 1212838, member: 70559"] I started using the boron nitride recently in a borrowed .308 with Sierra 155 grain plastic tip boat tail bullets. A twelve shot string averaged 2,808 feet per second in an 18" barrel. No indication of high pressure to me, but what do I know. The bolt worked like factory loads. Since I am new to both the nitride and the .308 is this about what one would expect without the coating? [/QUOTE]
