winchester WB 115g 9mm OAL variances

[tb-av]

I'm getting drastically different 115g 9mm in WWB.

It's enough to see and feel in casually handling the ammo. It all works fine but I thought this was rather unusual.


Box that I bought a couple weeks ago.

1.094


Box I bought yesterday

You'll find that with WWB. prior to reloading years ago I found that measuring and grouping WWB by OAL that it shot more consistent POI particularly the batches from 1.135 - 1.145

Ok, thanks. I didn't know if this was abnormal or what. It seemed like such a drastic difference I didn't know if the short ones were getting into a danger zone.

I'm still gearing up to load 9mm. Need to buy some dies before I can start shooting my own loads.
