My early 700 Mountain rifle in .280 was the only Remington I've never been able to shoot. It was a 2 1/2" rifle when I did everything right using custom loads, bench rest techniques, etc. Even caved in and let a smith work on it and the best we could do was 2 1/2". I killed elk and deer with it but when it wouldn't even deliver 2 1/2 I sent it down the road. Told the buyer it wasn't a shooter but he said he could fix it, never heard back.
Sharing my experience since everyone else's was different.
