If you lived in Pennsylvania, you could bring it to my house with a couple of boxes of shells and I would guarantee you that if I sighted it in that it would be right.
I gave my dad a .270 Gamemaster once that would shoot two 140 gr bullets in the same hole at 200 yards. He called me a liar one day and I took the gun, after being in the gun cabinet for 5 years, wiped the dust off it. Put a shell in the chamber, pulled the trigger, bulls eye.
Took the empty shell out, had my brother put a piece of masking tape over the hole and shot a second time and all you could see from the back side of the target was the masking tape pulled through the hole.
A perfect .270 hole in the target and nothing else.
