no i haven't shot blackhorn out of my white and i never will i have my loads figured out. i wanted to buy this new cva especially for the blackhorn 209 and the federal game shok combination. the cva guy told me to expect some failure to ignite using the bp that came in the rifle so why would i want to use it ? and furthermore i shouldn't have to modify a new rifle when cva could have very easily just put both in there for me to have either option the bigger point here is me as the consumer "my money " my opinion on the money i spent if i had known that it would have been such a hassle i would have bought a knight rifle which i really wanted to do but being that i'm sending this gun back home to sit in my buddies gun safe until i go home to hunt i didn't want to have a knight rifle just sitting there. i hoped i explained my situation well enough for everybody understand but doesn't seem to be the case?
