Years back I bought a 7mm and did a chamber spec check, got a safe length but longer than recommended for the bullet, ran powder and tests and got a good round.
Then I had a hunting trip and found I had not reloaded when I was low. No time to reload and get the gun checked outg, it, so I grabbed what I could find that was cheap (Federal Premium back then) , down to the range for the sight check and it was as accurate ad the hand loaded.
So, for as little as it got shot (anyone shoot a 7mm Mag recreational? - could not with the recoil absorbers but then..... ugh).
I just grabbed a couple of boxes of the Federal each year and life was good.
