Ok so I recently bought several boxes of Nosler 130 Grn Ballistic Tips, in 270,from Nosler which will be kept for hunting and three packets of 130 Grn Nosler Ballistic tip BLEMS, from Shooters Pro Shop, for the first time. Opened all three plastic bags, 50 Bullets in each bag, and separated all the 150 bullets by weight, a few at 129.6 ; 129.8 and lots of them 129.9 ; also lots130.0 and 130.1. 1 bullet out of 150 was 130.5 grns. Not so good. I saw no visible discoloration of the jackets. The yellow tips look just fine, but I did not have "magnifiers" on as I observed them. Just my regular glasses. That was Good!!! So, I have lots of factory new Nosler 130 grn bullets , and a few packets of these 130 Grn Blems separated by weight. Set for several seasons both at the range and in the field , for the 270 Win deer Rifle. Use the blems for taking friends to the range and hit paper at 100 yards, just for fun. I remain a big fan Nosler Bullets!!!
