Funky land and groove marks, Savage 10 6.5 creed

[JFoley001]

Um,  I've never seen this before. 60 rds down the pipe,  147 ELDM. Never seen marks like this. Rifle won't group for shit, nowhere close to out of the box savage accuracy I'm used to. Whatcha think?

Have you ever looked down the barrel of your other savages? Mine all look like train tracks just like above. Savage rifling is notorious for tool chatter marks, though generally they still shoot well.

Yeah that's ugly but not unheard of in Savages.

Figured I'd give it a chance before slapping a prefit in it's place. My other Savages weren't noticeable to the naked eye, not like this.

try a different bullet before abandoning the barrel.

I just ordered a 12fv in Creedmoor for cheap.  Hopefully it doesn’t gave this problem. What kind of groups is it shooting?

[JFoley001]

Of about a dozen groups, I was able to get 2 five-shot groups to 1/2 moa @ 100 yds. That was using Hornady factory 147 ELDM of the same lot number. Gonna whip up some 140 ELDM and try again. ES and SD were 55 and 18, respectively over 10 shots.  2573 avg at 66F out of the 24" bbl.

Standard Savage.  Non-lapped barrel.  Those are reamer marks.

Just a thought, I don't have experience with Savages new AR lines but check the polymer tip for damage after chambering.  I'd cycle a couple through by manually locking the bolt to the rear then hitting the release next time at the range. If the tips are getting jacked then that would be your answer.

Bolt gun, single loading. 

 

If it were an AR, I wouldn't expect the same accuracy.
