Pac Nor price is reasonable. Any idea of their turn around time?

It's been suggested that I pick up one of the lower cost Husky's in 9.3x57 with a good bore and have that barrel rechambered to 9.3x62 as I've heard that many do. Not a bad idea, but here's where my ignorance shows. I thought the 57's were .358 bore and the 62's .366 bore. Isn't that enough difference to cause issues? Or what am I missing?
