I have an opportunity to buy a very good condition model 66-2, with a 4" barrel. I would be shooting mostly 357 magnums in it, and I've read that this is a problem with the model 66.

Is the issue only with the higher speed lighter weight bullets, like the 115 & 125gr JHPs, or also with the 158gr JHP?

If I am only shooting 50 rounds a week of 158gr .357 through the gun, would I experience any issues?

When (and if) I return to inspect the gun before purchase, is there anything in particular I should be looking for?

Thanks again!
