[QUOTE="Bart B, post: 562614, member: 5302"] There's nothing wrong with full length sizing that case. You may well get best accuracy with it sized that way. And seating long, heavy bullets' heels below the neck won't hurt accuracy. .300 Win. Mags. shot in competition have used 200-gr. HPMK bullets so seated and were very accurate; both with new and properly full length sized cases. Uneven release of the bullet is caused by uneven neck tension. Proper full length sizing with a bushing die (no expander ball) will make very uniform neck tension on bullets, especially if the case necks are turned to a uniform thickness and the right size bushing's used.
