617 barrel leading up
I have a 617 10 shot 6" barrel. I have bin shooting JHP ammo (federal,,winchester) and the barrel leads up really bad after 50 rounds or so.I have ran about 1000 rounds through it and its not getting any better, anyone have any ideas why this is happening

.22 LR ammo is not jacketed, but it does have a coating on the bullet that may be fouling the bore. Does the clean bore look shiny and smooth?
At pistol velocities I don't think that .22s would leave lead deposits, but if I am wrong someone will be along to correct me soon...

Do you see lubricant, copper or lead fouling?

It appears to be lead .I shoot this same ammo through my buckmark,henry and m&p 15 22 and I can shoot around 500 rounds before I clean them,I do not understand why the most expensive gun I have does this after only 50 rounds and it also loses its accuracy

I had the same thing happen with my Ruger mkiii. It would fill up with so much lead I couldnt drop a string through it.
Sent it back to Ruger. They said they drill the bore on a 10 ft or whatever length and then chop it into pieces and machine the rest. When it was machined it was machined backwards. Apparently the threading is uni-directional. I'm still surprised by it but per Ruger their threading only works one way.
No clue if S&W is the same way. Maybe it's your problem???

Sorry for all the questions. A call to S & W customer service seems to be in order. If they will not help, there are methods to lap or smooth centerfire bores but I am not sure if this is used for rimfires also.

That sounds fishy. As I remember years ago Colt used a left hand twist and S&W a right hand twist in their barrels. Both shot well.

I have had this happen when shooting Remington Thunderbolt which has HV plain lead bullets. I attributed it to the plain lead bullets.

I had the same problem with a new model 63. Met the s&w rep at a gun shop grand opening and advised sending back to factory. They cut the forcing cone and replaced the cylinder. Appears to be much improved.

I aggree with the suggestion of sending the gun to S&W for them to look at. I have a 617 no dash and leading has NOT been a problem whatsoever. At the velocities produced in the 617, leading problems would indicate that the fired bullets are being "torn up" by some mechanical means.
I would suspect rough bores in the chambers, a poor forcing cone, or a rough bore in the barrel. With all these possibiliities on the list, it's best to let the factory deal with it. After all, that is what warranties are for and S&W has a great reputation for Customer Service, so give them a chance to fix it.
Just be aware they do shut down for a couple of weeks in August, so it may be another week or two before you get a response.

Before I sent it in I spoke with a tech. When I told him the issue he first asked if it was a SS gun. They all ready had received a couple of the other mkiiis that were made with the reverse-milled batch from the one stock of barrel.
Seems odd to me, but everything they said matched up.
