I think it'll make you a fine project myself. I just picked up a 511-X today. C&R is nothing but trouble. :bthumb:
It is unfortunate, but this 511 just doesn't shoot well. At 25 yards groups are pretty consistently 1.25-1.75" regardless of ammo used. I gave it a thorough cleaning when I got it and only ran patches with Hoppes #9 after. I've also had 2 other people shoot it and they can't get better than 1.5" groups. I've checked it over and the crown looks fine and the bore looks good, but there is a dark ring just after the chamber ends. I took a pic, but you can't really see the rifling just before the ring. The ring goes all around the bore, except for from about 9 o'clock to 7 o'clock. I've tried brushing it out and though I have got more grime out, the ring is still there. I've been suggested to try J B Bore Brite, so I may give that a go, but I'm beginning to think I need a new barrel. I found one on Gunbroker that has been drilled and tapped all over for $12, but I don't really want all the extra holes.
Btw, heres the pic I took of the ring
Just keep soaking & cleaning, when you think it is clean then get some Kroil-oil and go at it again. Kroil is a penetrating oil/cleaner and will deep clean the pores of the metal.
As my bore cleaner I mix Kroil and Hoppes 50/50, then for the final I use straight Kroil.
Also use a 22 cal. bore mop, it will put more juice in the barrel.
I have a CZ V22 8mm rifle, it took two weeks of soaking & cleaning to get all the 70 years of krud out of the barrel, but she finally came clean.
Its all good. Once I get the barrel from GB I'd probably be up for a trade on the front sight that'd cover the holes. I've got a receiver peep on the way, so with a new front sight, I wouldn't need either front/rear that I have with that. I'll PM you when it gets here.Another option with that ring is to put a cleaning rod segment with a bore brush into a hand held drill and go at it. That ring may also be erosion from shooting many shorts. I have a 510 barrel like that and it is eroded BAD from shorts. I was unaware until I pulled the barrel from the action.
Mr Quija, congrats on the extra barrel (I lost). I would not have bid against you if I realized you were RFC family. The post style front sight will cover those screws holes. Its like a 513 sight but contoured for the smaller barrels. I have one of them, perhaps we could work out a trade for your old barrel, let me know.
