I have three S&W 629s, a 6.5" -4 Classic, a 6" -1 and a 5" -3 Classic DX. Although I am a handloader, I can't see setting a loader up for a recipe I will shoot perhaps a half-dozen shots of a year (including an annual zero check) so I also use only factory loads for hunting. All three of those 629s shoot the Hornady 240-grain XTP load with great accuracy and the bullet's on-game performance is highly regarded.
In fairness, I must state that I only hunt deer with that cartridge so I can't speak for its performance on hogs.
As a side benefit, that factory load shoots to the same 25-yard point of impact as my handload of a 240-grain cast SWC over 10.0 grains of SR4756 and at 50 yards, the added drop of the handload is less than an inch so I can use my handloads for practice without continual sight adjustments.
