Good Afternoon all,
This is my first post here and I've read many interesting articles so far that have been beneficial to me for my shooting. I've just purchased a brand new Sako rifle in 300 WSM and was sighting it in. One box 150gr Silver ballistic tip ammo shot around a 1 inch group, another box with a different lot number shot a .192 " group. I've seen this happen to me before.
I would like to know how to track down specific lots if possible, in order to purchase a few more boxes. The good box is much older than the other box as far as when I purchased from store. I've got a Winchester Model 70 in the same caliber that is VERY finicky and that is why i need to find the same lot. That way hopefully I can shoot the same box of ammo with both rifles if I carry them both on a trip as a backup.
Thanks in advance.
