I had two boxes of the 30'06. At the range, from the bench, I got horrible groups at 100 yards. The groups were very inconsistent. The rifle I used was capable of sub-one inch groups and these were five to six inches.
Thinking it was possible, though unlikely, that I was having a really bad shooting day

, I gave the second box to an older man (WW2 Marine armorer) and asked him to try them in his rifle. He shot 10 rounds, two five shot groups, and gave them back. He didn't even want the brass. His groups mirrored mine. I shot the last ten with the same horrible results.
I have no idea why they shot so badly, but we ended up leaving the now once-fired 40 rounds of brass behind when we left. I doubt the brass had anything to do with the results, but why take a chance?
The only good thing about that ammo was that it had been given to me by an FFL so I had no money in the stuff.
I was so surprised by the performance that I took the same rifle out the next week to make sure nothing was wrong with it.
The rifle, with other ammo, shot its usual good groups.
But, the felt recoil with this ammo was, indeed, less.
I can load reduced loads, & get less recoil with the same level of accuracy my rifle is capable of, so I would not spend my money on Remington's Reduced Recoil ammo.
YMMV of course.
