I had an FAL import 308 assault rifle that barely put rounds on the paper at 50 with the sights moved all the way. Figure it had a bent barrel, because where it did hit they were tight.
Rossi is my vote for all time worst. Got one of their "Encore" style guns that you can switch out barrels on. Got the 22mag and 223 with plans on getting at least two more. 223 was all over the place, bad enough that when I moved out to 200yrds half the rounds didn't hit the paper. The 22mag wasn't tempered correctly. I would sight it in, then the next trip to the range first 3 rounds wouldn't hit the target. 4th was the extreme right of the paper, subsequent rounds would continue to move into the center until by 8 or 10 it was on the bull again. Took a bath on that one and bought two Savages in the same calibers. Been happy, and hitting the bull continuously, since.
In my book Rossi's are only good as boat paddles or door stops. Maybe tomato stakes.
Remember, shoot straight and shoot often.
Good... Bad... I'm the guy with the gun.
