Just an observation:
If you have a stock of this ammo, I'd suggest you begin cycling it out. We're getting quite a few split necks/cases that are not rifle related. All three rifles(actually 4 barrels as I just had my spare 77/17 barrel threaded and swapped it in last month) we're currently shooting are showing the case splits. Even Tom's tight chambered CZ has case body splits. Some of this ammo is 10 years old. I haven't seen this happening in more current production lots.
This unfortunate as I'm an ammo hoarder and tend to stock heavily on ammo that works well in my rifles.
