I shoot 777 in my CVA Mountain Stalker/Bobcat all the time with no problems and excellent accuracy.
Cayuad,
Did you do anything special to get 777 to shoot in your CVA? When I tried it in mine I had a lot of misfires where the cap would go off but not ignite the powder. I tried tapping on the far side of the lock, with the lock facing the ground, to make sure that some powder went into the bolster but I still had misfires using a standard #11 cap and the factory nipple. I never had any trouble with Pyrex or Goex.
Thanks,
Bob
