As someone else posted, in those days Ruger barrels were .003" oversize to prevent this sort of event. That load was hot in the original barrel if you got loose primers at 5 firings.
Good to know about the older Ruger barrels.
I never disussed the (short?) case life with anyone, just figured 5 reloads was par for the couse on a high pressure hunting round.
As I have a number of loads worked up for the old barrel looks like I've some serious bullet pulling in my near future.
