Got the Bone Collector back from TC
Well i finally got the bone collector back from TC. I shipped it back to them because it was shooting 10" groups at 100yds,and sometimes it wouldnt even hit the 2' x 2' target. I removed the scope and replaced everything. I took the brand new Nikon Omega scope off and returned to Cabelas and got the Leupold Ultimate slam, tried that and still the same thing. I read over on MM of another person having the same trouble who i contacted. They straightened his barrel and returned it, and he still had problems. They did the same to my gun and now it seems to be shooting good. I took the ultimate slam scope back and got the Nikon Omega again. Here are some targets from my first trip to the range since i got gun back from TC. I mounted the Nikon Omega back on and boresighted it. It was really windy , so i decided before i left, no scope adjustments, just shoot some different combos all with 90g and see what happens........... All these groups were from 100yds.

"Straightened" the barrel? Heck, I'd be a little irritated like that, you paid for a premium gun you should get a barrel that's right, not wrong then jury-rigged to be acceptable...I can't imagine you can totally straighten a bent barrel.

Premium Grade
When the long hole is initially drilled through the length of the barrel, 90% of the time it has a slight curve. The barrel is then mechanically straightened before final turning. When excessively heating the barrel by "Rapid Firing", the barrel tends to return to it's original curved condition. It then moves back to straight when cooled. This can cause groups to "walk" slightly as the barrel heats up and cools. Barrel companies set aside the 10% of barrels that were drilled so close to perfect that they didn't require straightening and stamped these "Premium Grade". Therefore, a premium is no better steel. It basically means "unstraightened". For hunting guns, and heavy barreled guns, it should be considered.
