[QUOTE="tacomHQ, post: 2886900, member: 67159"] Could you show a bore scope record along points in the barrel at "blank number of rounds"? I would be interested in seeing how much material is bonding to the bore. We have appraised barrels shooting a bit larger round at slower speeds- that have fully packed the lands to the point they were hard to identify. The throat was clean, the muzzle was clean but the center 12+inches was essentially a smooth bore. The clean ends I overall attribute to the operators cleaning methods. It just took 80 patches and many hours to clean the "smooth bore" out. While not shooting anywhere near those speeds we have shot 256gr rounds at 3450 during a match. Approximately 50rounds. By the last shot the group had opened to 2moa. Cleaned it - back to 3/8moa. In hunting a good round down a fouled/prepped bore is not a concern. Degradation within your required boundaries is another thing/issue. What have others seen for barrel conditions when comparing solids to standard jackets? Don't mean to hijack this thread. Let me know if there is an issue... [email]john@tacomhq.com[/email] [/QUOTE]
