    I loaded up some 25-06 deer loads using 115 Partitions. While checking BTO measurements, I was getting two different measurements with ~.030" difference. WTF? I take a closer look at the bullets. The bullets are two different shapes. One shape is pointier, has a smaller opening (~.146") in the jacket for the lead tip, the lead tip has a sharper point and overall length is longer ~.1.140". The other shape is blunter, larger opening (~.151") and is shorter at ~1.085". All weigh ~ 115 grains. I emailed Nosler last Monday, no response yet. Any 25 cal shooters that use this bullet know what is going on? Mike

    Call nozler, email don't work! Throw them 115's in the garbage and get some 80ttsx barnes bullet's . they are way better in every respect.

    Please go back and read my introductory post and in particular, the last sentence which is the question.

    I think what happened is I dumped the few remaining bullets I had in one box into a newly opened box. This was last year when I was done loading for hunting. The old box I managed to dig out of the burnable trash. Yes, they are different lot#. One would hope lot to lot variation would not result in such a radical difference in shapes. Maybe I had a batch of the old screw machine bullets from forty plus years ago. Doubt it. Just tried to call Nosler. Put on hold for 20 minutes. Finally got answered by voicemail. Left a message, hopefully they will call back. This is why I tried the email route first, I hate elevator music.

    Just got off the phone with the Nosler rep. They have indeed changed the shape, made them pointier. The old boxes I bought about 8 years ago, IIRC. He thought the change was a smidge before that, I probably got some old stock. Mike

    Been using the Nosler partitions for years now in my 25-06 and have had nothing but success on Mule deer and Elk. Would guess you have to different lots and the dimensions will vary slightly.

    If you're shooting inside 250 yards I would not worry and just shoot them.

    When you go to sight them in, shoot some of both just to make sure.

    Or you can just segregate them.

    I had a similar experience with the 115 nosler ballistic tips for my 25-06. I had a fair number of some older bullets that I used for practice and plinking. got around to opening up a new box, and found that they had not only changed the size of the plastic tip, but also the shape of the ogive, which lead me to have to change my seating depth. really kind of a pisser when you've already got a good load worked up.
