[QUOTE="toliver, post: 1213573, member: 74698"] So I did a test. Took a 300wsm Browning X bolt LRH and shot a control group. With clean barrel. Velocities are as follows with bare barrel and bullets with known load that is minute of deer. 3099 3125 3121 3092 3086 3007 no idea what this was. Next group is barrel cleaned copper etc with clean patches as end result. Followed by two passes with HBN alcohol solution. Same bullets coated vibratory style no media. 3037 3032 3020 3043 3040 3005 cold fouled 45 minute rest. Impact in group of following 5 shots. 3041 3036 3045 3036 3020 Improved about .25 moa. Did measure but could tel by looking at target. Velocities told me a lot! [/QUOTE]
