Good luck with the rifle. My 257 Roberts is a 1989 M77. Not an ultralight but easily my favorite rifle and very accurate. I think I'd take the rest of the ammo apart and burn the powder with a match. Or sell it back.

Check the throat when you get a chance. My guess is you will find it is quite long, as is mine and as are the throats on several of my Rugers from that era. I've always joked the bullets in my Roberts couldn't touch the lands with a stick, but it doesn't hurt accuracy. Best 3-shot group I've ever shot was with that rifle, .232" center-to-center @ 100 yards, 75g V-MAX.

Used the Roberts and a 110g AccuBond @ 3163fps MV to shoot a buck antelope in Wyoming two days ago. 300 yards on the run, quartering a bit into a 20mph wind.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.

A good .30-06 is a 99% solution.
