In addition, he said the barrel was bulged. That right there says a LOT! You DON'T bulge a barrel on a Ruger without shooting faulty loads (usually reloads), and firing squib loads behind each other, or extremely hot loads. In my opinion it's a testament to Ruger's strength that it didn't blow up.
Sometimes you earthlings REALLY amaze me!
I too find it hard to believe that Ruger would not fix the problem unless there were undue circs(reloads, negligence etc.) on the part of the shooter. I have 2 gp100s and an sp101 both are built like TANKS so hurting one must have been gross negligence. As to a Taurus vs a Ruger south american metalurgy is not equal to American made.
I too have the feeling that we are not being told all of the story. I've owned many SA and DA Rugers over the years and find that as strongly as they are built cracking a barrel is probably self inflicted, squib load or a double charge of fast burning powder in a handload is more likely the problem. Rugers ARE the strongest revolvers made IMHO, so the finger has to point back to the owner.
