GunGeek,

To summarize and very very briefly in my opinion the big take away from my case was the TCA Encore can not keep tolerances and head space grows overtime, especially with larger calibers like I was shooting (300 win mag).
In my trial we had 3 guns with excessive head space. My gun was well out of spec., A gun with 5 shots was out of spec., A gun with no shots was out of spec.

The excessive headspace allows gasses to act on the plunger thus allowing the gun to open. (We are not talking about a bolt gun here….the plunger is held in place with a spring That supposedly needs to be replaced after so many shots that they never tell you about.) The stock breaks in bending when the gun blows open…very violent.
