That MagTech load is at 807 FPS ....so its a little faster than I would prefer...but its not too heavy a load for a J frame.
Whether you like shooting it in a J frame or not ...vs something a little slower is another issue / but it sure won't hurt the gun.
Hitting your buddies up for reloads is a bad idea...it makes them assume all of the liability for you shooting their ammo. I won't load for -- or sell -- any reloads to my friends ...I don't want the responsibility or the liability.
Just buy commercial ammo ....or invest in your own reloading setups down the road...you'll be a lot better off in my opinion.
