I do reload. What I've found is that, due to the 10's small case, it can go critical very easily.
I'm really impressed with double Tap's 200 gr. wide flat point bullet and their quick, friendly serice. The 200 gr. ammo, however apparently clocks about 1150 fps.
There is some less than full power ammo out there. Federal's HydraShok ammo is only loaded to about 980 fps with their 180 gr. bullet. Reminnton's UMC 180 gr. FMJ and CCI's aluminium cased stuff is also loaded light. But the premium stuff like that from Hornady and Winchester appears to be right where it needs to be. E
