Re-barreling Rugar #1 22-250???

I think its shot out cause it went from shooting bug holes for many years to shooting 8-12 " groups that are all over the place. I cleaned it well, checked optic, mounts, & rail. It wasn't new when I got it and has had a lot of rounds shot by me not counting what the original owner did. Should I be trying something else??
I would say check the crown for damage if accuracy went away that quickly.
a bore scope should tell you how the barrel is ahead of the chamber, which is where most barrels "burn out".
It is actually throat erosion and can be fixed by cutting 1/2 inch off the chamber end and rethreading and rechambering for the original cartridge.

I'm really surprised by the comments here.
The 22-250 is a known throat eroder. I have seen more than one with the throats pushed out a couple of inches. The main cause for this is max+ loads and using the wrong powders. It also takes 2-3000 rounds or more. This is not an unusual amount for some varmint hunters. It is definitely better than the hot loads in a 220 Swift but it still happens. Recently, I pulled a barrel on a Rem 700 to replace it with a take off barrel from a CGNer. I didn't swap out the barrel because I wanted a faster twist rate. I got one in the new to me barrel but the main reason was because the throat was pushed forward at least 3+ inches. My round count through that barrel was 2765 over a period of 2 years. I was really having a good time with gophers out past 300 yards. My cousin's place was crawling with the little rodents. Almost infested.
Anyway, decent accuracy was no longer attainable. Minute of gopher was impossible, other than luck. Even a shot on a coyote out to 200 yards was iffy.
Guntech is right, replace the barrel with a new one. Maybe even think about going to a different cartridge if the 22-250 isn't useful for you. A good 243Win, 257Rob or 7-08 are some other choices that will use the same extractor. Anything that utilizes the same bolt face as a 30-06 is a likely candidate. Anything smaller or larger, will require a new factory extractor.

I'm surprised you didn't suggest the most obvious choice for rebarrelling a .22-250, .250 Savage standard version or AI. It would allow the OP to use his .22-250 brass till its worn out and make a great gun for varmints and deer sized game.
