Hand lapped or New Barrel?

I have a Ruger M77 in 7X57 that my father bought in the ealy 1980's that has a badly (to me) tool-marked barrel. Accordingly, the accuracy is sporadic. Currently, it is of little more value than a conversation piece. Nothing I would take into the woods anymore. I have learned over the years that such a thing was not unique to my one rifle. I like the appearance of the existing bbl. and the 7X57 original chambering makes it further appealing. Sitting there costs me nothing. I have an excellent 308 that does everything i would require from the 7X57, so there is no urgency. Is hand-lapping by a gunsmith an option for this or should I just throw in the towel and send it to Shaw's and get it rebarreled? (Rebarreling would not be done in 7X57. Probably 280 A.I. to differentiate it from the 308)

Have you tried anything else?Some of my Savage barrels are rough looking and they shoot just fine.They seem to foul quicker and take longer to clean but for a normal hunting rifle that shouldn't be a concern.

I'd try taking some JB bore bright to it and see if you can polish it up yourself.

If i had the money i would have the barrel changed.
It is tough hand lapping a barrel. JB just never did it for me. I tried it a couple times ?

I wold also check the bedding and make sure everything is tight, the stock may need bedded or something tightened. Dave Bruno in Dayton Pa. is a good gunsmith to check out your rifle.

I had that sense, that a straight change of the barrel would be for the best. I didn't want to alter the essence of the rifle, but if there isn't a good remedy to a st-st-st-stutter-stuttering rifling tool job, so be it.

jb should help take out light tool marks. there are also some rounds that supposedly smooth out the barrel. I know they could be purchased loaded in 308 not sure about 7x57.

I agree with Drags. There are many other things I would look at before replacing the barrel. Ruger 77s are sensitive when it comes to bedding. That is where I'd look first.

Is it bedded? Does it need to be bedded?

Is the barrel floated or bedded? If its floated it might need some pressure. If its bedded it may need to be floated.

How is the crown? The crown is much more critical to accuracy than tool marks in the barrel.

Rough barrels do not necessarily affect accuracy especially "hunting" accuracy.

If you might have to rebarrel anyways, it doesn't hurt to mess with it a bit on your own.
