I've got a CVA Hawken rifle (I bought it new in the early 90s) that's been hanging on my wall for nearly 30 years and never been fired. Now that I'm retired and getting back into shooting I want to take it out to the range. Is there a recommended relatively local shop (I'm in Annapolis) that will have the #11 caps, powder (black or substitute), patches, and .490 balls in stock? Or is that hit or miss and I will need to cobble what I need together from various sources? Thanks.
