[QUOTE="Michael Eichele, post: 326521, member: 1007"] 12x in 308 win. is actually optimum for 175-180 grain pills. The box states 10x but they are WAY off the optimum twist. With that factory 26" 12x I would be trying 43.0-45.0 grains of VARGET under that 178 at 2.800-2.825" OACL. Make any needed adjustments to the powder charge as needed. Your velocity should be close to 2750 and scary accurate. It is a caliber specifec sweet spot for those remmy varmint barrels. [/QUOTE]
