7.21 FIREHAWK

The following data was developed in a LAZZERONI 2000 rifle with a 28-inch stainless steel fluted barrel. As with all LAZZERONI rifles that I have seen, this one was extremely well made.

The rifle arrived a short time before a planned hunting trip to Zimbabwe. I only had one type of premium hunting bullet on hand.
