Dumb question

Depending on how your bottle attaches to the wildcat, and given the available room for the new bottle's diameter and neck length, there is a longer skinnier bottle for sale. Its discussed within this thread:

NO. 

OP...Look at the construction of the WC center structure. A bottle will never work, at least not practically. The tube removes easily, you not going to put a 3+ inch diameter bottle directly into the action... The center support hold the trigger. tube, barrel, and scope....

The standard sized WC .25 should be worth 50ish shots. My compact gets 35ish but I turned the reg up a bit so maybe really 28-30ish now,
