The T/C is of known engineering, made in the US to a consistant quality level. I have no issues placing an Encore chambered in 338 WinMag six inches from my face, because I know that the Encore platform was designed to take such usage.
The Optima line was designed around black powder, and has slowly been moving towards supporting some (223 and 243, so far) centerfire smokeless barrels. The QA and QC of the CVA stuff in general has been pretty spotty over the years, since they simply import stuff built to losely defined specs. I'm not saying that the Optima is crap, but it surely was not designed first-n-foremost to be used for high pressure smokeless centerfire chamberings.
I'd not want to be an early adopter of the CVA centerfire stuff, especially when you can buy a NIB Encore for just over $500 and used ones nicely appointed sell for $450 or less.
But that's just me.
