Thread: Hmm what have I done wrong ?

So I case gauge every round I reload, 223, I use a Dillon case gauge picked up from Reloaders.

OAL is 2.20", round checks fine on the gauge with the base flush and no raised primer, and it drops out of the gauge easily, but it's too tight for the rifle and I can't close the bolt. All 223 rounds are resized, and trimmed prior to loading. This has happened to @3 rounds in my last batch of 50, everything else has shot straight and accurately which was good news for me, bad news for the magpies.

Hmmm, any thoughts pls on what I've done wrong ??
