revolver Leading issue

[Phauxtoe]

I have had a Smith 617 for about a year and half.
been shooting mostly Federal Auto match.

I was cleaning it last night and noticed a build up of Lead in the space between the top of the frame and forcing cone.
what is the solution to this build up?
any ideas?

What is the cartridge it's chambered for?

Edit: Looked it up-.22LR? What I've noticed with the Federal Auto Match is the lead bullets appear 'dry', little if any bullet lube used. This could be a contributing factor. It would appear that a portion of the bullet is being 'shaved' when the bullet exits the cylinder, and contacts the forcing cone. I would try a different brand of ammo, or different type (i.e. copper-plated) and see if the problem persists.

good idea, but dammit the ammo shoots well out of it!

My 10/22 will feed almost anything-even Remington Subsonic hollow points-without a hitch. It does not like Federal Auto Match. Jams at least once per 10 round mag. Sold the other 4 bulk cartons I had.

There shouldn’t be any “shaving”at all of the bullet when it enters the forcing cone. If so, that would typically indicate an undersized forcing cone or possibly a timing issue. Are you getting any lead particles spittnng out from the top strap , or is it just an excessive amount of build up? After how many rounds are you seeing the build up?

its a 1.5 years old and i shoot it regularly but not excessively. a few thousand rounds?
I will photograph it tonight and post a photo here tomorrow.

Then I assume there is no cylinder play or end shake? Lock up is tight?

its Tight!

I get the same thing in my revolvers when I shoot lead. There is no shaving or misalignment in mine. I think its being deposited as the hot gasses escape past the gap between the cylinder and forcing cone.

The best solution I've found is a little Hoppes and some careful quality time with a dental pick.

 

[Phauxtoe]

it is shooting Very accurately, so perhaps until i do change ammo, i will use a dental pick also!

 

[S&W Fan]

Yup, then the culprit is monst likely due to the fact that Federal Match lead ammo is rather dirty. I use it often myself and find that after several hundred rounds some cleaning is necessary from lead foul build up.

Why not go with a plated bullet. That's all I use in my 10/22 for the same reason.

Why not go with a plated bullet.

Cause we gotta use up all that ammo we panic bought and stockpiled!!!

 

[Phauxtoe]

what Standard Velocity plated bullets are there?

Most , if not all standard velocity .22 target ammo ( 1150 fps or lower) are coated LRN .
The high & hyper velocity ammo are typically copper plated.

There are none that I’m aware of

Not familiar with revolvers but a member from PA gun forum had mentioned something about timing in revolver and excessive lead build up even some blowing out like shrapnel from cylinder

 

[Phauxtoe]

usually if the timing is off the revolver is not accurate, this thing is very much so!

Yup, it’s just a lead fouling issue common with many revolvers that get a steady diet of SV target ammo.

Here is the issue

I shoot my 617 in steel challenge and use Fed Auto match too.
Same build up, just gotta keep an eye on the area and clean it every once and awhile.
I also use Plated 36grn HP CCI mini mags too, but not enough for any build up to occur.
The Auto match is one of the cheapest bullets that are 100% reliable with a 7.5 lb trigger pull and it's also very accurate in my 617 too.
I've also had no problems with loading and ejecting them from the cylinder, even after hundreds of rounds fired.
After cleaning the lead buildup from the area, I soak a Q tip with Kroil and coat the area.
The kroil makes the lead buildup easier to remove.

Don't sweat it.

Then my filing cabinets would be empty and I wouldn't know what to do with them!

What you're describing is not that unusual for the 617. I have one with thousands of rounds thru it and have used it for steel challenge. Regular cleaning will be your friend. I simply use my favorite solvent coupled with a nylon toothbrush.
