I had a rifle go to hell a few years ago and started shooting like a shotgun.

I had just bought 2 boxes of Remington golden ammo in the 500 +- .

They were so bad when i got home i checked the rifle/scope and they were fine.

Didn't have much going that day so i brought my scales to the house and sorted them.

I had 3 weights light,normal and heavy.

The next day i shot them sorted into weights and the rifle and ammo went back to shooting tight groups like before.

Don't know what their problem was at that plant but they were screwed up.

I have not done it since but it was eye opening for sure.
