.264 pet load is a 129 grain Hornady at 3300fps with H-870. It's been in my 24" Savage 110. I got 3200fps with factory 140 winchester! 100 grain factory Winchester didn't do much faster. Now I've moved from MT to NC and two of 3 rifles I've bought here are .264's. Both are pre-64 Winchesters, a featherweight (1962) and a Westerner (1960). Has anyone seen one marked "Westerner"?
