If you suspect the hammer is not striking square over the nipple, take a soda pop can and cut a chunk out of it with some tin snips. (Careful with that metal I always cut myself) put that over the nipple and fire the hammer down. This should show you how hard the hammer is hitting and where it is hitting in relation to the nipple imprint that will be on the can too...

The hammer not being center on the Bobcat is not all that uncommon. I have read a number of posts which the same thing happened. My understanding is, they cold bent the hammer in a vice. I am not going to recommend you do that because it is your rifle. You might want to call CVA if it shows they are not hitting square and see what they suggest. Others I have talked to on these boards just went ahead, removed the hammer and bent it just a little a time until it was hitting square.

I am sure a gunsmith reading these posts can give you better information on how to fix the hammer should it be off center. Also make sure when you seat your caps, they are seated all the way down on the nipple. If not, sometimes the first smack of the hammer will seat the cap to the proper position and then the second smack will fire the cap....

Good luck with the rifle..
