i went a different twist 1-10 reason in Berger book was posted better twist for 60 gr. bullets for a 220 Swift we use 60 gr. Nosler partitions for coyote hunting with dogs that reason is too not ruin the coyote hides they still have some value if the hide does not have big holes in hide. the 220 Swift is still my favorite all time varmint cartridge , 2nd would be the little old school 22 Hornet .
