Guess I'm a new member again. I was registered here before, but I had to re-do it today. Anyhoo, I have a 29-5 and a 629-4 both with the underlugged barrels, and I understand these have the "Endurance Package" in them. Wondering what the general consensus is on using the heavy bullet (like 300gr.) bullet loads in these guns. I keep 'em out of my 29-2's, wondering how these models would hold up. Thanks for any help!
