Don't know about the Newer CVA's?
But My First Muzz was/Is a CVA Hawken!
Both Me & My Friend bought identical Guns the same exact time!
Mine when loaded with Pyrodex was like Shooting a Flintlock!
Delayed/Relayed Ignition every time!
My Friends Gun Would Fire just Fine with Pyrodex!
Mine didn't Like anything but BLACK NASTY GOEX 3fff Powder!
We compared the Nipple Diameters/I Bought a New Nipple & Same BS!
Started using the Stinking/Smoking Black Powder & Never looked back!
I'd get some & Try it if I were you!
Or get some Fresher/Different Powder & Try that!
Just because You mighta bought it thinking it was Fresh doesn't mean it's Fresh!
I'd Try another Nipple/Breech Plug as Well!
Back Me Off to 1,700 Yards,650 is a Little Close & I'm Not Comfortable with it!
A GUT SHOT at 1,700 Yards will Still Make Some Good BRAGGIN Rights so I Can Say I At Least Hit Him!
