How bad is steel case ammo on bolt action rifle extractors

I have a chance to trade for a boat load

The only real issue I've had shooting steel .303 Brit and 8mm is occasionally I had one that would stick and fail to completely extract. Steel is harder than brass so it doesn't expand and contract like brass. It also, IMO, tends to run a little dirtier, mainly carbon buildup, than brass.

Usually I can recycle and it clears but I've had to use a Leatherman type multi tool to clear it three or four times over the years. Kind of a minor hassle but nothing that ruined my range day.
 
To answer your question I would guess unless your shooting a thousand rounds of steel a day once a week for a month you might, maybe, get a little extra extraction wear but for a typical range day I wouldn't worry about it. Also, some steel case ammo use bi metal bullets that are pretty useless when trying to zero at 50 yards or more.
 
 I regularly shoot steel 9mm Tul Ammo through my CZ EVO Scorpion. Never had a problem with any of it and at $6.00 a box why not.

An informal study pitted various kinds of .556 ammo against one another. There were brass loads from all the major manufactures, against steel cased rounds from major companies like Brown Bear and the major Russian manufacturers. I think like 10 or 15 (more or less) identical AR-15 rifles were used to actually shoot the ammo as well.

The study concluded that by 9,000 rounds, the steel cased ammo had all but worn the rifling totally away, leaving the barrel so shot-out that the bullets all keyholed (hit the paper sideways) at 100 yards.

I'd say to hell with the extractor; worry about the bore more.

I don't see how steel cased ammo could have any effect on the bore.
If we are talking steel jacketed ammo then I'm surprise it made it past 900 rounds before the bore was worn out.

Much depends upon the coating used on the ammo.

Traded for some Fed. 7.62x51 and some surplus German & Turkish 7.62x51 ammo

Will see how they perform in my Savage Axis
