Brass coloring on bolt & bolt head- normal?

[rawfuls]

I know for a fact there was a thread just like this one, I think on a Ruger American.

In any case, I took the Remington 783 in .223 out to the range today, shot a solid 60 shots through it, was able to teach two new buddies to shoot- I think I got one of them hooked
It's JUST about zero'd in at 25 yards, need to pick up some match grade ammo to zero it in perfectly.

Pulled the bolt so I could store it separate, and found brass colored specks throughout the bolt, as well as on the bolt head. Is this normal? I'm shooting some cheap bulk Federal .223 55gr FMJ's.

Will be cleaning the guy tonight with some Break Free CLP- and if you all think it needs it, some Hoppes 9.

Looks pretty normal.
You could spend 15 minutes with some 400 grit sandpaper on a popsicle stick and take off any sharp edges that might be catching on the cases.
That will reduce the time it takes the gun to otherwise smooth out on itself and stop scraping brass from the cases.

Coolbeans!
I'll go ahead and just keep on cycling it, putting more and more rounds down range!

Will need to do a proper cleaning later this week, I got too lazy

looks au natural!

Normal for a factory gun. Only a high polish would stop that.

I have a $1350 custom action that does the exact same thing, mostly due to surface finish I picked. I have a polished action that doesn't. No big deal, shows that you use it!

Just about sighted in at 25 yards after 60 shots?
Wow, That's just not right. Might want to check your scope mounts

The first time I took it out, I threw about 25 rounds through her, just to get the feel; didn't touch the dials.

Second time I took her out, same dealio.

The third time was this Friday, and I only started trying to dial it in after about 40 rounds in.

The majority of the times the rifle's been shot, was to teach new shooters.
I never really attempted to sight it in until just recently, mainly because I didn't have the time... little did I know it's real quick and easy

While I'm talking about getting it zero'd in, if I'm attempting to get it zero'd to 100 yards w/o using 100 yards, I should be doing it at about 15-20 yards, right?
Considering 25 yards is equivalent to 200 yards, or so.

My largest use of range will be 100 yards, so I want to dial it into 100 yards; but the 100 yard range isn't quite open yet

25 is the same as 300 with AR sight height. It will not be true on your bolt rifle. I would zero it as far as you can up to 100yrds. At 25 the bullet has barely started to travel and you will not have a very good read off of it.

Just out of curiosity why no 100 yrds? If I bore sight I am always on paper at 100.

I will as soon as our 100 yard range opens up, until then it's about 40, maybe 50 yards at best.

I usually run about 50 rounds to warm up the barrel and then shoot 25 round groups at 10 yards, 15 yards, then 20 yards, then 25 and so on until I get a good zero at 100 yards. It's the best way to verify you have a spot on zero.

At the end of if, I take the scope off and remount it and check my zero to see if the scope mount is doing its thing. If not, I start the whole process over at 10 yards.

OMG almost forgot to mention! You need to use as many different types of ammo as possible during this process.. that way you get a baseline average. ;D

The last time I saw that amount of brass shaving on the a new Ruger Bolt the bullets were just bouncing-off the paper target at 50 yards.

Save yourself some bucks and switch to cheap-0 steel case .223 and keep shooting.
