I haven't but I will tell you that it's a waste of time given the limitations of the 357 cartridge. depending on whether you're shooting 38 specials to save money, or 357 +p for hunting, you can see as much as 3 feet point of impact change at 100 yards. the variance from round to round, unless you are trickle loading your own, is just too great to consider the 357 a precision cartridge and even then anything past 100 yards is seriously pushing the capabilities of the cartridge for any practical purpose. doing a trigger job on a pistol cal carbine is a little bit like giving MR T a boob job, it's a hard working practical rifle but it's never going to look pretty on paper.
