The Wolverine is easier to clean because after the barrel is removed from the stock there is one screw that holds the trigger assembly in place. Once that is removed it is like cleaning a pipe. The Black Diamond is a little more complicated and you have to clean from the breech to the muzzle to avoid pushing anything back into the trigger assembley. On the Wolverine once the trigger is pulled it makes no difference. Also the Black Diamond's striker assembly is a little bit of a pain to pull. You remove the locking back lug and spring assembly then you pull the striker back, then you have to reach into the breech with your fingers or something and push that striker just a little more backward to where you can get a grip on it. In the Wolverine, you unscrew the back part and pull the whole striker assembly out the back end of the rifle in one piece. The Wolverine is also more easy to clean at the range if you like....

I bought my Wolverine from Natchez.Com for $149.00 . Mine shoots the #11 caps and I have not had a single problem with the rifle and the ignition at all. The Black Diamond XR shoots the 209 primers. I have noticed that after about seven shots, the 209 nipple seems to get loose, and at times the rifle will actually drop the primer if you tilt the barrel upwards. All you need do is clean the nipple with a Q-tip and it solved the problem. The Black Diamond also seems to get a lot of blow back out of the breech. The Wolverine is not so bad.
