That is good advice and I am already shopping.
I have a lot of 45-70 brass, 100 Remington .458 JSP 405 grain bullets and may buy some .458 400 grain Speer bullets and plenty of powder, so I plan to shoot mostly hand loads.
BTW, this is my first Beretta firearm, so I am learning as I go. So far, it seems to be well made, smooth to operate, and has nice features like articulated front trigger, articulated cross bolt, and graceful metal and stock work. Very accurate barrels too; both will put bullet after bullet into the same hole if the shooter does his part.
