Thanks for the continuing report of experiences.
Mule Deer - I'd be particularly interested in how you prep a new floating bolt head rifle for DBC. I think I have this 223 barrel free of copper - using Wipe Out and a plastic Jag I see no blue, only a bit of pink and the barrel is so clean that some jags with a Pro-Shot patch cannot be pushed down the barrel.
So - how much farther should I go before DBC? Should I give thus barrel 100 strokes with J-B?
Today a bottle of Montana X-Treme Copper Killer finally got here - from Montana. I can do a few courses of that, if necessary.
Thanks
