Hope that helps.
Increasing headspace would tend to make that problem worse.
I was just about to post about having the headspace checked...but I won't do it now! ;D
As well as not saying anything about headspace, I won't mention that in my experience with the 222 family of cartridges, a CCI magnum primer or a Remington 7 1/2 has either lessend this problem or made it go away.
