I agree that using the abrasive bullets to lap a bore should be a last resort. I think the most noted is "Tubbs Final Finish". We may reach a point of havig to resort to it though. I find some of todays rifles from US manufacturers pitiful. This all encompassing obsession with the "botom line" certainly isn't helpful to the buyer. Remington was a cut above, but they're no better than the rest now. My last one was a Remington 700BDL in .25-06 that shoiyuld have never got out of the factory. Just one mans opinion. Best wishes.
