Bolt Won’t Close with New Prvi Partizan Ammo
I've got a brand new .243. Sighted it with Hornady American Whitetail 100 grain round sand the bolt worked just fine. Tried Prvi Partizan 90 grain rounds today and the bolt won't close easily. There are lots of posts on other forums about reloaded ammo that causes this problem but nothing about factory ammo.
I don't have machinist's calipers to measure overall length but according to a cheap set of woodworking calipers that measures in hundredths of an inch, the Prvi is 2.60 and the Hornady is 2.583. Base diameter is .468 for both. Primers appear to be recessed .02.-03 from the base.
Strange that the bolt closes with one manufacturer's factory load but not with the other. Any idea what to check next?
I'm also going to get in touch with the ammo vendor and Prvi.
