Are trimming pilots interchangeable between manufactures ?

[Puma]

Are there any differences between trimming pilots ? Are Lyman the same as RCBS or Forster ?

The only difference I could think of would be the diameter of the shaft.

Could someone with a micrometer post the actual diameter of the shafts ?

thx

Shafts are different on some. I have at least 2 sizes.

Redding, Hornady and Forster are the same size shank.

RCBS is smaller (can work in a pinch with some tape or pop can shims and a bit of care in setup in place of the above makes). Lyman is also smaller and different than RCBS if I remember correctly.
