I have a new 629, really like this gun, and the largest ammo shot thus far is 240 grain magtech. I would like to know what the largest grain bullet I can safely shoot in this gun, when calling S&W they were not much help because they said 240 grain is the most I should shoot and I know that people shoot more. Home loads for it are 180 grain corbon jhp, but for range shooting I would like to try more and am open to suggestions. Any help would be appreciated. The same question would also apply to a Taurus snub nose ,2" that I recently purchased, a 605 model and not an ultra lite.
