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.

CASES: LAZZERONI
SCOPE: LEUPOLD 3.5-14X LPS in LAZZERONI MOUNTS
All groups were 3 shots at 100 yards. Cartridge over all length was 3.570 inches.
