I can't help thinking this is going to have problems with "Hey, I used smokeless powder like it says,

why'd it blow up?"  Nevertheless, it is a nice step for a bunch of people, a muzzleloader designed to use specifically Blackhorn 209 or one of two smokeless propellants.  New CVA Endura, with a bolt-action breech.

According to their site, 

APPROVED PROPELLANTS FOR THE ENDURA
"Blackhorn 209 is CVA’s all-around recommended propellant for the Endura rifle, as it is both a great performer and legal for use during most muzzleloading hunting seasons.

However, since Blackhorn 209 can sometimes be hard to find, the CVA Endura was designed to also be usable with specific types and amounts of modern smokeless rifle powders. These approved smokeless rifle powders are IMR 4198 and VihtaVuori N120. Be sure to check your local hunting regulations before using such modern smokeless rifle powders for hunting."

WARNING: THESE ARE THE ONLY APPROVED PROPELLANTS FOR USE IN THE CVA ENDURA. DO NOT LOAD ANY OTHER TYPES OF MODERN SMOKELESS POWDER, INCLUDING OTHER SUCH POWDERS DESIGNED FOR PISTOLS, SHOTGUNS, OR RIFLES, IN A CVA ENDURA.

So no black powder, it would seem.  Just saw this this morning, be interesting with bullets work best with it, and what kind of accuracy.
