I've loaded quite a bit of 06 and never had anything close to 68 yrs..i guess I trying to make the case for the extra expense of the 318.plus I have a rack of 06s.i do like that kynoch makes ammo at a reasonable (for an odd British caliber).I did layaway the perfect donar rifle last week custom German sporter double st triggers and a khales scope with German mounts.its an 06 and I have six or seven now so trying to talk myself into a rebarrel
