Shaving lead?

[elginrunner]

While shooting a new to me gp100 match champion, i notice every once in a while something hit my cheek. This is at full arm extension, double action firing. Im using 158 swc gc.

Couldnt find my pictures at first.

Does that look like leadon the sides, it's not the same color as the carbon .....

Sounds like the timing might be off.

Single action or fast double action?

If it's a load on the lighter side, I've noticed powder flakes hit me before. It can happen with any load, but is much more noticeable on light, or dirty burning loads.

That doesn't look too extreme.

Do you have a range rod to confirm cylinder alignment?

Are the firing pin marks centered on the primers?

[elginrunner]

I placed cardboard next to it and fired 12 rounds. No lead, but flects of lube. I use ls carnuba red. It’s a fairly warm round of 2400 powder @ 1250 FPS.

The primers are struck centerish, not perfect, but as close as I’ve ever seen on a revolver.

I do have the yellow thingy and will check it out.

Not fast, but double action. I stage my trigger pull.....

How about barrel/cylinder gap? Friend of mine bought a gp100 that did the same. He called Ruger and he ended up sending it back. IIRC the cylinder/barrel gap was about .002" less

Sounds like you answered your own question.

No. it is not shaving lead.
