Thanks for the replies. Went to the 2 largest bolt and nut distributors in the Phoenix area, they have some in stainless, but not long enough for the rear and I would need to grind the head a bit smaller in circumference. Will call WBY today and check Midway. I found some at the bolt dist. a few years ago that fit my 30/378 and .257 WBY Mark V's, but they must not be available now. Should have purchased several sets extra.
