I just bought a new cva at the tulsa gun show this weekend it is a inline 209 magnum and there was a video that came with it with instructions on the use of all CVA muzzleloaders and in the vidio the fellow that was doing the presintation said that you are never to use 150 grains unless the gun is a magnum. He also said that the triple 7 was hotter and you must reduce the load by 20% and if you are using the pellets then the mfg. has already done that. In compairing tripple 7 with pyrodex you will see that the tripple 7 are much shorter. He also suggested that if you did not get or have lost your owners manual that to call or write CVA and they will send you one right out. If you did not get a video with your gun you might contact them for one it has a world of info on it, also lots of safty tips.
