[QUOTE="Bart B, post: 641626, member: 5302"] Back when I was wearing out 7.62 NATO Garand barrels shooting matches, I often checked M118 match ammo for bullet runout. That arsenal match ammo often had rounds in some lots that ran as much as 7 to 8 thousandths runout. Using a .338" bullet puller collet to hold live round's case neck indexed to the high point, I would bend them back straight pushing on the case head. 'Twas easy to get runout down under 2 thousandts. 600 yard accuracy went from about 1.5 MOA down to about .6 MOA. Did the same thing with government issued .30-.338 Win. Mag. ammo from the marksmanship unit. Well worth the effort to do so in my opinion. [/QUOTE]
