New gunsmith built 7mm Remington Mag. At first the bolt would not lock on round then would not extract case when it did lock on the round. Gunsmith fixed that problem 'sort of' bullets load but won't extract factory loads half the time but will extract handloads most of the time. Bullets hit target sideways....everyone..... point orientation variable. 50 yard target placement. Blackhole Weaponry barrel 1:10 Polygonal rifling 700 action Bell & Carlson stock. Trigger is a rebuilt (unknown origin) Shot in rifle; Factory bullet, Winchester 175 gr. Handloads Nosler brass WLRM primer Berger Bullet Hunter Classic 168 gr. H4831 SC 62 gr Has muzzle break installed. The rifle is beautifully built but bullets hitting 16 X16 target at 50 yds, right, left bottom no pattern at all, but all hit sideways. At 100 yds could not hit paper at all. Barrell problem? I have taken the rifle back to the gunsmith to fix the other problems (kind of) but what would cause bullets to always strike sideways? Could the extraction problem also be part of an overall barrel problem? Any thought or help would be appreciated. Earl L.
