Thanks for sharing the information on the Gold Dot load.

By firsthand reports, the Airweight frame crack 'seems' to be due mostly to over-torqued barrels, sometimes related to use, or is found with an inspection (as in, no definite cause).

If it were my gun I would use this load sparingly if it is very controllable with multiple fast shots and groups well for you. If you've found another load that meets these criteria (158 gr SWC/HP, or even 148 gr WC) I would tend to use those. Good luck in your decision.
