As a devout disciple of Jack O’Connor, I just love 270 Winchesters, having at least six rifles in that calibre. Remington 700’s are good if you don’t get the occasional lemon, Winchester Mod 70’s are classics with the featherweight a truly beautiful light rifle. But the Tikka T3 HB Varmint in 270Win is truly an incredible machine. We used 130g Sierra bullets pushed by 55grains of IMR4350 to kill groundhogs out to 970 yards while trying to get into the Varmint Hunter’s 1000 yd club here in Ontario. The Varmint Hunters club and groundhogs are since long gone but Jack O’Conner’s pride and joy 270Win still lives on.
