For one thing, the cartridge is cheap to reload and component bullets are easy to come by. You can even use unsized cast revolver bullets if you can get somebody to get you some that close to your bore size. I wouldn't use 458 WinMag's in it unless it was an emergency. The shorter case will fire-etch the area ahead of it and make the Lott brass flow into the fire-etched area, therefore stuck brass. Accuracy is as good as what you can hold without flinching. The Lott in my Ruger was a bit light and I added weight to it.
