Criticism
The .257 Weatherby Magnum is one of the most overbore cartridges available. The cartridge rates higher on the overbore index than the .264 Winchester Magnum and the 7mm Shooting Times Westerner but less than the 7mm RUM and the .30-378 Weatherby Magnum. The consequence of burning a large quantity of powder and driving a bullet faster is poor barrel life and throat erosion all of which affects accuracy and usable life of the firearm. Giving the barrel time to cool between each discharge of the weapon and following recommended cleaning procedures will help mitigate this issue and extend the usable life of the firearm chambered for this cartridge.
Earlier .257 Weatherby Magnum rifles had a twist rate of 1 rotation in 12 in (300 mm), which is too slow to stabilize long for caliber bullet. These bullets include most Barnes' bullets over 110 gr (7.1 g) and any conventional spitzer bullet of over 115 gr (7.5 g). Hornady's 117 gr (7.6 g) round nose bullet is made for such firearms which have the slower spin rate. Norma loads this bullet in the Weatherby's H257117RN ammunition for owner of such rifles who require a heavier bullet.

Famous quotes containing the word criticism:
“People try so hard to believe in leaders now, pitifully hard. But we no sooner get a popular reformer or politician or soldier or writer or philosopher—a Roosevelt, a Tolstoy, a Wood, a Shaw, a Nietzsche, than the cross-currents of criticism wash him away. My Lord, no man can stand prominence these days. It’s the surest path to obscurity. People get sick of hearing the same name over and over.”
—F. Scott Fitzgerald (1896–1940)
“It is ... pathetic to observe the complete lack of imagination on the part of certain employers and men and women of the upper-income levels, equally devoid of experience, equally glib with their criticism ... directed against workers, labor leaders, and other villains and personal devils who are the objects of their dart-throwing. Who doesn’t know the wealthy woman who fulminates against the “idle” workers who just won’t get out and hunt jobs?”
—Mary Barnett Gilson (1877–?)
“... criticism ... makes very little dent upon me, unless I think there is some real justification and something should be done.”
—Eleanor Roosevelt (1884–1962)
