Your Model 29-2 is safe to shoot with any commercial ammo. My experience with 44 Magnum ammo of recent manufacture is it's fairly moderate in terms of blast and recoil. It is true that some specialty ammo makers load much hotter and the stuff is way expensive. If you stick to name brand stuff...Winchester, Remington, Federal your gun will last longer than you will.

Now stop worrying and have fun!!
